Overview
Features
Features
Efficiency features
- Adaptive gate drive for maximum efficiency at any load
- Typical supply current in no-load operation below 250 µA
Application features
- Operates in an output voltage range between 18 V and 0 V
- Drain sense pin capable of handling input voltages up to 100 V
- Self-supplying for operation with a low output voltage
- Self-supplying for high-side rectification without the use of an auxiliary winding
- Operates with standard and logic level SR MOSFETs
- Supports USB BC, QuickCharge and smart charging applications
- HVSON8 package
Control features
- Adaptive gate drive for fast turn-off at the end of the conduction
- Undervoltage LockOut (UVLO) with active gate pull-down
- Blanking input for low and high switching frequency
- Enable input for CCM operation and for disabling at start-up or shorted output
