Cheron ASD & IPAD Marketing ACST2 Series NEW HIGH IMMUNITY, ROBUST 800 VOLT ALTERNATIVE CURRENT SWITCHES The home appliance industry is shifting towards electronic control on a worldwide basis. Together with this trend, electronics can now cope with AC mains constraints where high voltage robustness and transient voltage compatibility are the key challenges. ST has designed the ACSTM and ACTS devices to control the numerous AC loads necessary for the appliance process. These AC switches meet the requirements of reliability, compactness and mass production capability. The new ACST2 series belongs to the AC power switch family built around the ASD technology. These high performance devices are adapted to home appliances or industrial systems and drive loads up to 2 A such as pumps, fans or solenoids. ACST2 embeds a Triac structure with a high voltage clamping device to absorb the inductive turn-off energy. Thanks to its crowbar auto-protection technology it withstands line transients such as those described in the IEC 61000-4-5 standards. This component needs a low gate current to be activated (I GT < 10 mA) while providing a high electrical noise immunity such as those described in the IEC 61000-4-4 standards.

Criscione Power MOSFET Marketing STD55NH2LL STD55NH2LL Power MOSFET HIGH SIDE SOLUTION TO BOOST SYNCHRONOUS BUCK CONVERTER EFFICIENCY The increasing demand for greater power from the latest CPUs means that synchronous buck converters used in Voltage Regulator Modules (VRM) and POLs must have very high performance in terms of overall electrical behavior during switching transients and ON state. This demand may be satisfied by using low voltage Power MOSFETs in VRMs with very low gate charge (Qg) and low on-resistance RDS(on). The efficiency of the overall system can be improved with STD55NH2LL STD55NH2LL, ST's new high side Power MOSFET, in the synchronous buck converter. STD55NH2LL STD55NH2LL General Features R DS(on) * Qg industry' benchmark Conduction losses reduced Switching losses reduced Low threshold device High avalanche ruggedness Low gate drive power losses Device Comparison In order to demonstrate the benefits of using STD55NH2LL STD55NH2LL, a test was performed on the L6710 L6710 controller demoboard assuming the same low side switching and the following conditions: Vin = 12 V Vout = 1.5 V 2 phase: 1xHS, 2xLS Tamb = 25 °C fsw = 440 kHz The comparison made against two similar high side Power MOSFETs in DPAK, shows that the STD55NH2LL STD55NH2LL is an optimum solution to boost the efficiency by 1% in synchronous buck converters.

Menescardi Industrial and Power Conversion Marketing L6566 L6566 Multi-Mode Controller VERSATILE CURRENT-MODE PRIMARY CONTROLLER IC FOR HIGH-END ADAPTERS AND FLAT TVS L6566 L6566 is a new, extremely versatile current-mode primary controller IC specifically designed for high-performance offline flyback converters. Both FixedFrequency (FF) and Quasi-Resonant (QR) operation are supported by the same product; the user can pick either depending on the application requirements. L6566 L6566 is a multi-die product, including a high voltage section (HV start-up) in BCD off-line technology and a low voltage section (the core of the controller) in BCD6 technology, mounted together in a small, standard SO-16N SO-16N plastic package. Functional Description The device features an externally programmable oscillator which defines the converter's switching frequency in FF mode and the maximum allowed switching frequency in QR mode. When FF operation is selected, the IC works like a standard current-mode controller (UC384x-like) with a maximum duty cycle limited at 70 % min. QR operation, when selected, occurs at heavy load and is achieved through a transformer demagnetization sensing input that triggers the Power MOSFET's turn-on. With a very small load, in FF or QR operation the IC enters controlled burst-mode operation that, along with the built-in non-dissipative high-voltage start-up circuit and a reduced quiescent current, helps keep the consumption from the mains low while meeting the most demanding energy saving regulations. L6566A L6566A And L6566B L6566B L6566 L6566 is supplied in two orderable versions, L6566A L6566A and L6566B L6566B. L6566A L6566A is specifically designed for offline flyback converters operating from a front-end Power Factor Corrector. The L6566A L6566A provides an interface with the PFC controller that turns-off the pre-regulator at light load. L6566B L6566B is designed for offline flyback converters where a front-end PFC is not expected. L6566B L6566B has a frequency modulation input that modulates the oscillator frequency. This modulation is used to reduce the peak value of EMI emissions. www.st.com/powermanagement Main Features And Benefits Selectable multi-mode operation On-board high-voltage start-up Low quiescent current (< 3 mA) Adaptive UVLO Line feed-forward Pulse-by-pulse OCP Transformer saturation detection Latched or autorestart OVP Brown-out protection Component count minimization Fits all world-wide energy regulations Rectified mains voltage Vout DC PFC controller Rectified & filtered mains voltage L6566A L6566A L6566B L6566B Vout DC System block diagram Typical Applications Hi-end AC-DC adapter / charger LCD/CRT monitor, LCD / CRT TV Digital consumer Single-stage PFC 6 By M.

Valvo Voltage Regulator & Interface Marketing STLQ50 STLQ50 Voltage Regulator 50 mA, 3 A SUPPLY CURRENT LOW DROP LINEAR REGULATOR EXTENDS BATTERY LIFE The optimization of the low quiescent current in power supply designs has become of great importance. A long battery life is essential and depends on the consumption of the power supply at a given load. One way to decrease the consumption especially at low output loads is to minimize the quiescent current of the power regulator IC. There are portable applications where the device is required to work at full load for a very short time only, while it has a very long stand-by time. In this case a very low quiescent current helps. STLQ50 STLQ50 Description As a result of this market demand, ST has developed the STLQ50 STLQ50, a BiCMOS linear regulator specifically designed for operating in environments with very low power consumption constraints. Due to the very low quiescent current (3 A) the device extends the battery life in applications with a very long stand-by time. The Power MOSFET pass element also allows a very good drop-out figure (200 mV at 25 mA I out and 350 mV at full load) without affecting the consumption characteristics. Main Features 2.3 V to 12 V input voltage range 50 mA maximum output current 3 A quiescent current Available in 1.8 V, 2.5 V, 3.3 V, 5.0 V fixed output voltage and in adjustable version 200 mV dropout voltage at 25 mA output current Internal thermal protection Small SOT323-5L and SOT23-5L packages Small Packages ADJ GND V bandgap 1.22 V OUT + STLQ50 STLQ50 N/C ADJ IN Short circuit and thermal protection Adjustable Vout Vin Fixed Housed in the very small SOT323-5L (SC-70 SC-70) and SOT23-5L packages, the device fulfils the space saving requirements of battery powered equipment.
