Download the HF920BGSE datasheet PDF. This datasheet also includes the HF920B variant, as both parts are published together in a single manufacturer document.

General 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.

Key Features

  • such as VCC under-voltage lockout (UVLO), overload protection (OLP), over-voltage protection (OVP), and short-circuit protection (SCP). The HF920B is designed to minimize EMI for power line communications (PLC) in home and building automation.
