HF920B 900V, Fixed-Frequency, EMI-Optimized Flyback Regulator with Ultra-Low Standby DESCRIPTION The HF920B is a flyback regulator with a monolithic, 900V MOSFET. The HF920B is an enhanced version of the HF920 with EMI optimization. It provides excellent power regulation with very few external components for AC/DC applications that require high reliability, such as smart meters, large appliances, industrial controls, and products powered by AC grids. The HF920B uses peak current control mode to provide excellent transient response and easy loop compensation. When the output power falls below a given level, the regulator enters burst mode. The IC is also optimized to achieve very low power consumption during standby conditions.
