General Description
The TPS92315 flyback power supply controller provides isolated output current regulation without the use of an optical coupler.
The devices process operating information from the primary power switch and an auxiliary flyback winding to provide precise output current control.
Key Features
- 1.
- Primary-Side Regulation (PSR) eliminates opto-coupler.
- ±5% LED current regulation.
- 130 kHz maximum switching frequency enables high power density SSL drivers designs.
- Quasi-resonant valley switching operation for highest overall efficiency.
- Patent-pending frequency jitter scheme to ease EMI compliance.
- Wide VCC range (35V) allows small bias capacitor.
- Drive output for MOSFET.
- Protection functions: over-voltage, low-line,.
