SSL4120T

Resonant power supply control IC with PFC

Features and benefits

2.1 General features

 Integrated PFC and HBC controllers

 Universal mains supply operation (70 V to 276 V (AC))

 High level of integration resulting in a low external component count and a cost

effective design

 Enable input (enable only PFC or both PFC and HBC controllers)

 On-chip high-voltage start-up source

 Stand-alone operation or IC supplied from external DC source

2.2 PFC controller features

 Boundary mode operation with on-time control

 Valley/zero voltage switching for minimum switching losses

 Frequency limiting to reduce switching losses

 Accurate boost voltage regulation

 Burst mode switching with soft-start and soft-stop

2.3 HBC controller features

 Integrated high-voltage level shifter

 Adjustable minimum and maximum frequency

 Maximum 500 kHz half-bridge switching frequency

 Adaptive non-overlap time

 Burst mode switching

2.4 Protection features

 Safe restart mode for system fault conditions

 General latched protection input for output overvoltage protection or external

temperature protection

 Protection timer for time-out and restart

 Overtemperature protection

 Soft (re)start for both controllers

 Undervoltage protection for mains (brownout), boost, IC supply and output voltage

 Overcurrent regulation and protection for both controllers

 Accurate overvoltage protection for boost voltage

 Capacitive mode protection for HBC controller

Applications

The device can be used in all LED lighting applications that require very efficient, low Total

Harmonic Distortion (THD), high power-factor, true universal input voltage and

cost-effective power supply solution between 10 W and 300 W."
