HF920BGS - EMI-Optimized Flyback Regulator

Download the HF920BGS datasheet PDF. This datasheet also covers the HF920B variant, as both devices belong to the same emi-optimized flyback regulator family and are provided as variant models within a single manufacturer datasheet.

Description

The HF920B is a flyback regulator with a monolithic, 900V MOSFET.

The HF920B is an enhanced version of the HF920 with EMI optimization.

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.

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.
