Functional description
SSL152x family 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. SSL152x family uses voltage mode control. switching 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 constant power constant current mode drive LEDs. 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. When some reason auxiliary supply sufficient, high-voltage supply also supplies 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 (typically dB).

Valley switching
cycle started when primary 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: where: primary self-inductance parasitic capacitance drain node soon oscillator voltage high again secondary stroke ended, circuit waits drain voltage before starting primary stroke. Figure shows drain voltage together with valley signal, signal indicating secondary stroke voltage. primary stroke starts some time before actual valley ringing frequencies, some time after actual valley high ringing frequencies.

Demagnetization
system operates discontinuous conduction mode time. long secondary stroke ended, oscillator will start primary stroke. During first tsup(xfmr_ring) seconds, demagnetization recognition suppressed. This suppression necessary applications where transformer large leakage inductance output voltages.
Minimum maximum duty factor
minimum duty factor switched mode power supply maximum duty factor (typical value oscillation frequency).
OverCurrent Protection (OCP)
cycle-by-cycle peak drain current limit circuit uses external source resistor measure current. circuit activated after leading edge blanking time tleb. protection circuit limits source voltage VSOURCE(max) thus limits primary peak current.
Short circuit winding protection
short circuit winding protection circuit also activated after leading edge blanking time. source voltage exceeds short circuit winding protection voltage Vswp, stops switching. Only power-on reset will restart normal operation. short circuit winding protection also protects case secondary diode short circuit.
