Product Description

The UCC28070EVM is an evaluation module for UCC28070 300W, two phase interleaved, power factor correction pre regulator that uses average current mode control techniques to achieve near unity power factor. The pre regulator was designed to operate off a universal ac line input of 85V to 265V and provides a regulated 390V dc output. The UCC28070 is an advanced power factor correction device that integrates two pulse width modulators 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.
Inter leaved average current mode PWM control with inherent current matching
Advanced current synthesiser current sensing for superior efficiency
Programmable frequency (30KHz to 300KHz)
Programmable maximum duty cycle clamp
External clock synchronization capability
Programmable peak current limiting
Bias supply UVLO, over voltage protection, open loop detection, and PFC enable monitoring
External PFC disable interface
There are high voltages present on the pre regulator and it should only be handled by experienced power supply professionals.
