UCC28070A 180° out-of-phase interleaving operation significantly reduces input and output ripple current, and conducted EMI filtering becomes easier and less expensive. Features including frequency jitter, clock synchronization and slew rate enhancements further expand the potential performance enhancements. The UCC28070A device features output overvoltage detection, programmable peak current limit, undervoltage lockout, and open-loop protection.
Features:
1. Interleaved average current mode PWM control with inherent current matching
2. Advanced current synthesizer current sensing for superior efficiency
3. Extended range programmable frequency (10 kHz to 300 kHz)
4. Programmable frequency jitter rate and amplitude for enhanced EMI reduction
– Amplitude: 3 kHz to 30 kHz
– Rate: up to 30 kHz
5. Bias supply undervoltage lockout, overvoltage protection, open loop detection and PFC enable monitoring
6. Open circuit protection on VSENSE and vinac pins
