Description
The UCC3895 is a phase-shift PWM controller that implements control of a full-bridge power stage by phase shifting the switching of one half-bridge with respect to the other.
Features
- 1 Programmable-output turnon delay.
- Adaptive delay set.
- Bidirectional oscillator synchronization.
- Voltage-mode, peak current-mode, or average
current-mode control.
- Programmable soft start, soft stop, and chip
disable via a single pin.
- 0% to 100% duty-cycle control.
- 7-MHz error amplifier.
- Operation to 1 MHz.
- Typical 5-mA operating current at 500 kHz.
- Very low 150-μA current during UVLO
