Monolithic Power Systems HF920

The HF920 is a flyback regulator with a monolithic, 900V MOSFET. The HF920 provides excellent power regulation in AC/DC applications that require high reliability, such as smart meters, large appliances, industrial controls, and products powered by poor AC grids. The HF920 requires a minimal number of external components.

DESCRIPTION

The HF920 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. The IC consumption is also specially optimized. As a result, the HF920 achieves very low power consumption during standby conditions. MPS’s proprietary, 900V, monolithic process enables an over-temperature protection (OTP) that is on the same silicon as the 900V power MOSFET, offering the most precise thermal protection. The HF920 also offers a full suite of protection features such as VCC under-voltage lockout (UVLO), overload protection (OLP), over-voltage protection (OVP), and short-circuit protection (SCP). The HF920 is designed to minimize electromagnetic interference for power line communications (PLC) in home and building automation applications. The operating frequency is programmed externally with a single resistor, so the power supply’s radiated energy can be designed to block interference to the PLC.
