UCC28019DR General Description

The UCC28019DR is an 8-pin active Power Factor Correction controller designed for systems ranging from 100 W to over 2 kW, catering to a wide-range universal ac line input. Its startup current during under-voltage lockout is minimal, at less than 200 µA, providing efficient operation. Users have the option to control low power standby mode by simply pulling the VSENSE pin below 0.77 V, offering flexibility in power management
