FAN7631 Product details

Description

The FAN7631 is a pulse-frequency modulation controller for high-efficiency half-bridge resonant converters that includes a high-side gate drive circuit, an accurate current-controlled oscillator, and various protection functions.

Features

Variable Frequency Control with 50% Duty Cycle for Half-Bridge Resonant Converter Topologies.
High Efficiency with Zero-Voltage-Switching (ZVS).
Up to 600kHz Operating Frequency.
Built-in High-Side Gate Driver.
High Gate-Driving Current: +500mA/-1000mA.
Programmable Dead Time with a Resistor.
Pulse Skipping and Burst Operation for Frequency Limit (Programmable) at Light-Load Condition.
Simple Remote On/Off Control with Latch or Auto-Restart (A/R) Using FI.
