HF920BGS
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 ponents 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 pensation. 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.
MPS’s proprietary, 900V, monolithic process enables over-temperature protection (OTP) on the same silicon as the 900V power MOSFET, offering the most precise thermal protection. The HF920B also offers a full suite of protection features
, such as VCC under-voltage lockout (UVLO), overload protection (OLP), over-voltage protection (OVP), and...
