SMPS mains drivers
Rev. September 2008 Product data sheet
SSL1623PH Switched Mode Power Supply (SMPS) controller that operates directly from rectified universal mains. implemented high voltage EZ-HV (Easy High Voltage Silicon-On-Insulator) process, combined with voltage BiCMOS (Bipolar Complementary Metal Oxide Semiconductor) process. device includes high voltage power switch circuit start-up directly from rectified mains voltage. dedicated circuit valley switching built which makes very efficient slim-line electronic driver concept possible. SSL1623PH operate applications with power range SSL152x family would better choice power below required. most basic version application SSL1623PH acts voltage source. Here additional secondary electronics required. combined voltage current source realized with minimum costs external components. Implementation SSL1623PH renders efficient cost power supply system.

SSL1623PH heart compact flyback converter, with placed primary side. auxiliary winding transformer used indirect feedback control isolated output. This additional winding also powers more accurate control output voltage and/or current implemented with additional secondary sensing circuit opto coupler feedback. SSL1623PH used constant power mode constant current mode drive LEDs. SSL1623PH uses voltage mode control. frequency determined maximum transformer demagnetizing time time oscillator. first case, converter operates Self Oscillating Power Supply (SOPS) mode. latter

case, operates constant frequency, which adjusted with external components CRC. Furthermore, primary stroke started only valley secondary ringing. This valley switching principle minimizes capacitive switch-on losses.
Start-up undervoltage lockout
Initially, self-supplying from rectified mains voltage. starts switching soon voltage passes VCC(startup) level. supply taken over auxiliary winding transformer soon high enough supply from line stopped high efficiency operation. soon voltage drops below VCC(stop) level, stops switching restarts from rectified mains voltage.
Oscillator
frequency oscillator external resistor capacitor external capacitor charged rapidly VRC(max) level and, starting from primary stroke, discharges VRC(min) level. Because discharge exponential, relative sensitivity duty factor regulation voltage duty factor almost equal sensitivity high duty factors. This results more constant gain over duty factor range compared systems with linear sawtooth oscillator. Stable operation duty factors easily realized. high efficiency, frequency reduced soon duty factor drops below certain value. This accomplished increasing oscillator charge time. ensure that capacitor charged within charge time, value oscillator capacitor should limited approximately
Duty factor control
duty factor controlled internal regulation voltage oscillator signal internal regulation voltage equal external regulation voltage (minus multiplied gain error amplifier (typical dB). minimum duty factor switched mode power supply maximum duty factor (typical value oscillation frequency).
Valley switching
cycle started primary stroke when switch switched (see Figure After certain time (determined oscillator voltage internal regulation level), switch turned secondary stroke starts. internal regulation level determined voltage REG. After secondary stroke, DRAIN voltage shows oscillation with frequency approximately, Equation Where: primary self-inductance drain node. parasitic capacitance drain node.

soon oscillator voltage high again secondary stroke ended, circuit waits drain voltage before starting primary stroke. primary stroke starts some time before actual valley ringing frequencies, some time after actual valley high ringing frequencies. Figure shows typical curve reflected voltage This voltage output voltage (see Figure transferred primary side transformer with factor (determined turns ratio transformer). Figure shows that system switches exactly minimum drain voltage ringing frequencies kHz, thus reducing switch-on losses minimum. kHz, next primary stroke started before valley. switch-on losses still reduced significantly.

Demagnetization
system operates discontinuous conduction mode time. long secondary stroke ended, oscillator will start primary stroke. During suppression time tsup(xfmr_ring), demagnetization recognition suppressed. This suppression necessary applications where transformer large leakage inductance output voltages.
Protections
8.6.1 Overcurrent protection
cycle-by-cycle peak drain current limit circuit uses external source resistor (see Figure measure current. circuit activated after leading edge blanking time tleb. protection circuit limits source voltage VSOURCE(max) thus limits primary peak current.
8.6.2 Short winding protection
short winding protection circuit also activated after leading edge blanking time. source voltage exceeds short winding protection voltage Vswp, SSL1623PH stops switching. Only power-on reset will restart normal operation. short winding protection also protects case secondary diode short circuit.
8.6.3 Overtemperature protection
accurate temperature protection provided SSL1623PH. When junction temperature exceeds thermal shutdown temperature, stops switching. During thermal protection current lowered start-up current. continues normal operation soon overtemperature situation disappeared.
