It is specifically designed for high-performance offline Switch Mode Power Supplies (SMPS) with minimal external components. The integrated PWM controller features include: a fixed-frequency generating oscillator, Under-Voltage Lockout (UVLO) protection, Leading Edge Blanking (LEB), an optimized gate turn-on/ turn-off driver, Thermal Shutdown (TSD) protection, and temperature compensated precision current sources for loop compensation and fault protection circuitry. Compared to a discrete MOSFET and controller or RCC switching converter solution, the FSQ0170RNA FSQ0170RNA, FSQ0270RNA FSQ0270RNA, FSQ0370RNA FSQ0370RNA reduces total component count, design size, and weight while increasing efficiency, productivity, and system reliability. These devices provide a basic platform that is well suited for the design of cost-effective flyback converters, as in PC auxiliary power supplies.

Pin Configuration (Top View) Pin Definitions Pin # Name Description 1 GND Ground. SenseFET source terminal on primary side and internal control ground. VCC Power Supply. Positive supply voltage input. Although connected to an auxiliary transformer winding, current is supplied from pin 5 (Vstr) via an internal switch during start-up, see Figure 2. It is not until VCC reaches the UVLO upper threshold (12V) that the internal start-up switch opens and device power is supplied via the auxiliary transformer winding. FB Feedback. The feedback voltage pin is the non-inverting input to the PWM comparator. It has a 0.9mA current source connected internally while a capacitor and opto-coupler are typically connected externally. A feedback voltage of 6V triggers overload protection (OLP). There is a time delay while charging external capacitor CFB from 3V to 6V using an internal 5µA current source. This time delay prevents false triggering under transient conditions, but still allows the protection mechanism to operate under true overload conditions. IPK Peak Current Limit. This pin adjusts the peak current limit of the SenseFET. The 0.9mA feedback current source is diverted to the parallel combination of an internal 2.8k resistor and any external resistor to GND on this pin. This determines the peak current limit. If this pin is tied to VCC or left floating, the typical peak current limit is 0.8A (FSQ0170RNA FSQ0170RNA), 0.9A (FSQ0270RNA FSQ0270RNA), or 1.1A (FSQ0370RNA FSQ0370RNA). 5 Vstr Start-up. This pin connects to the rectified AC line voltage source. At start-up, the internal switch supplies internal bias and charges an external storage capacitor placed between the VCC pin and ground. Once the VCC reaches 12V, the internal switch is opened. 6 Drain SenseFET drain. High-voltage power SenseFET drain connection. 7 Drain SenseFET drain.

Protection Circuits: The FPS has several protective functions, such as Overload Protection (OLP), OverVoltage Protection (OVP), Under-Voltage Lockout (UVLO), and Thermal Shutdown (TSD). Because these protection circuits are fully integrated in the IC without external components, reliability is improved without increasing cost. Once a fault condition occurs, switching is terminated and the SenseFET remains off. This causes VCC to fall. When VCC reaches the UVLO stop voltage, VSTOP (typically 8V), the protection is reset and the internal high-voltage current source charges the VCC capacitor via the Vstr pin. When VCC reaches the UVLO start voltage, VSTART (typically 12V), the FPS resumes its normal operation. In this manner, the auto-restart can alternately enable and disable the switching of the power SenseFET until the fault condition is eliminated. 1. Startup: In previous generations of Fairchild Power Switches (FPSTM), the Vstr pin required an external resistor to the DC input voltage line. In this generation, the startup resistor is replaced by an internal highvoltage current source and a switch that shuts off 10ms after the supply voltage, VCC, goes above 12V. The source turns back on if VCC drops below 8V. VIN,dc ISTR Vstr Vcc 78% at 115 VAC and 230 VAC input) Low standby mode power consumption (< 0.8W at 230 VAC input and 0.5W load) Enhanced system reliability through various protection functions Internal soft-start (10ms) Line UVLO function can be achieved using external component Key Design Notes The delay time for overload protection is designed to be about 30ms with C8 of 47nF. If faster/slower triggering of OLP is required, C8 can be changed to a smaller/larger value (e.g. 100nF for about 60ms). ZP1, DL1, RL1, RL2, RL3, RL4, RL5, RL7, QL1, QL2, and CL9 build a Line Under-Voltage Lockout block (UVLO). The Zener voltage of ZP1 determines the input voltage that makes FPS turn on. RL5 and DL1 provide a reference voltage from VCC. If the input voltage divided by RL1, RL2, and RL4 is lower than the Zener voltage of DL1, QL1 and QL2 turn on and pull down VFB to ground. An evaluation board and corresponding test report can be provided. 1.
