HF920GSE - flyback regulator

Download the HF920GSE datasheet PDF. This datasheet also covers the HF920 variant, as both devices belong to the same flyback regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key 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.

HF920 900V, Fixed-Frequency, Offline Regulator The Future of Analog IC Technology w/ Ultra-Low Standby Power Consumption DESCRIPTION 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. 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.
