Description
STSR3D is a smart driver IC designed to provide high current outputs for driving secondary power MOSFETs used as synchronous rectifiers in low output voltage, high efficiency flyback converters. The IC generates a driving signal with set dead times based on the synchronizing clock input withdrawn on the secondary side of the isolation transformer.
Specifications and features
- SUPPLY VOLTAGE RANGE: 4V TO 5.5V
- TYPICAL PEAK OUTPUT CURRENT: (SOURCE 2A, SINK 3.5A)
- OPERATING FREQUENCY: 30 TO 750 KHz
- SMART TURN-OFF ANTICIPATION TIMING
- AUTOMATIC TURN OFF FOR DUTY CYCLE LESS THAN 14%
- POSSIBILITY TO OPERATE IN DISCONTINUOUS MODE
Application Scenarios
STSR3D is ideal for applications requiring high current outputs for driving secondary power MOSFETs in low output voltage, high efficiency flyback converters. It can be used in various power electronic systems that require synchronous rectification.
