The Future of Analog IC Technology HF900 900V Offline Switching Regulator DESCRIPTION The HF900 is a flyback regulator with an integrated 900V MOSFET. Requiring a minimum number of external components, the HF900 provides excellent power regulation in AC/DC applications that require high reliability. These applications include smart meters, large appliances, industrial controls, and products powered by unstable AC grids. The regulator uses peak-current-mode control to provide excellent transient response and easy loop compensation. When the output power falls below a given level, the regulator enters burst mode to lower the standby power consumption.
