UCC28951
- Enhanced zero-voltage switching (ZVS) range
- Direct synchronous rectifier (SR) control
- Light-load efficiency management including:
- Burst mode operation
- Discontinuous conduction mode (DCM), dynamic SR on/off control
- Average- or peak-current mode control with programmable slope compensation and voltage-mode control
- Closed-loop soft-start and enable function
- Programmable switching frequency up to 1 MHz with bidirectional synchronization
- (±3%) cycle-by-cycle current limit protection with hiccup mode support
- 150µA start-up current
- VDD undervoltage lockout
- Wide temperature range: –40°C to +125°C
The UCC28951 controller is an enhanced version of the UCC28950. It is a fully compatible drop-in replacement for the UCC28950. The UCC2895x devices use advanced control of the full-bridge in addition to active control of the synchronous rectifier (SR) output stage.
ZVS operation ensured over a wide range of operating conditions, while the load current naturally tunes the switching delays of the secondary-side synchronous rectifiers(SR). This functionality maximizes overall system efficiency.
