Description
The SSC3S900 series is a controller with SMZ
method for LLC current resonant switching power supplies, incorporating a floating drive circuit for a high-side power MOSFET.
SMZ: Soft-switched Multi-resonant
Features
- Standby Mode Change Function ▫ Output Power at Light Load: PO = 100 mW (PIN = 0.27 W, as a reference with discharge resistor of 1MΩ for across the line capacitor) ▫ Burst operation in standby mode ▫ Soft-on/Soft-off function: reduces audible noise.
- Realizing power supply with universal mains input voltage.
- Floating Drive Circuit: drives a high-side power MOSFET directly.
- Soft-start Function.
- Capacitive Mode Detection Function.
- Reset Detection Function.
- Automat.
