Description
- The UCC28070DWR is a 2-phase Interleaved CCM PFC Controller that integrates two pulse-width modulators (PWMs) operating 180° out of phase. This interleaved PWM operation generates substantial reduction in the input and output ripple currents and the conducted-EMI filtering becomes easier and less expensive. A significantly improved multiplier design provides a shared current reference to two independent current amplifiers that ensures matched average current mode control in both PWM outputs while maintaining a stable, low-distortion sinusoidal input line current. The UCC28070 contains multiple innovations including current synthesis and quantized voltage feed-forward to promote performance enhancements in PF, efficiency, THD and transient response. Features including frequency dithering, clock synchronization and slew rate enhancement further expand the potential performance enhancements.
- Interleaved average current-mode PWM control with inherent current matching
- Advanced current synthesizer current sensing for superior efficiency
- Programmable frequency (30 to 300kHz)
- Programmable maximum duty-cycle clamp
- Programmable frequency dithering rate and magnitude for enhanced EMI reduction
- External clock synchronization capability
- Enhanced load and line transient response through voltage amplifier output slew-rate correction
- Programmable peak current limiting
- Bias-supply UVLO, over-voltage protection, open-loop detection and PFC-enable monitoring
- External PFC-disable interface
- Open-circuit protection on VSENSE and VINAC pins
- Programmable soft-start
- Green product and no Sb/Br
- ESD sensitive device, take proper precaution while handling the device.
