SSC3S937 LLC Current-resonant Off-line Switching Controller 150mW
Sku:
SSC3S937
Features
- No standby aux supply required to meet 2007 EU 0.3W limit
- 125mW of available standby power from 0.27W input power
- Low audiable noise
- Auto restart
- Burst operation in standby mode to reduce idle power
- Soft start function
- Floating MOSFET direct drive circuit
- Ideal for universal mains input voltages
- Reset detection circuit
The SSC3S937 will meet the 2027 EU standby power limits of 0.3W and still be ready to deliver full power up to 500W without the need for an additional standby ac-dc converter. This represents a big saving in component count and design complexity. Furthermore several functions are built to the controller reducing even more the external component count.
In stand-by mode 150mW of power is available from 0.27W input power which is ample for most processors or standby circuits.
The IC incorporates a floating drive circuit for a high side power MOSFET, able to source 540mA or sink 1.5A of drive current
Useful functions such as: standby; mode change; automatic deadtime adjustment; overload protection with input compensation; and capacitive mode detection are included.
