Fairchild FAN7621SJX

隔离11.3V ~ 25V200 W

Overview

The FAN7621SJX is a PFM Controller for half-bridge resonant converters. Offering everything necessary to build a reliable and robust resonant converter, the FAN7621 simplifies designs and improves productivity, while improving performance. The FAN7621 includes a high-side gate drive circuit, an accurate current controlled oscillator, frequency limit circuit, soft-start and built-in protection functions. The high-side gate-drive circuit has a common-mode noise cancellation capability, which guarantees stable operation with excellent noise immunity. Using the zero-voltage-switching (ZVS)technique dramatically reduces the switching losses and efficiency is significantly improved. The ZVS also reduces the switching noise noticeably, which allows a small-sized Electromagnetic Interference (EMI) filter. It can be applied to various resonant converter topologies; such as series resonant, parallel resonant and LLC resonant converters.
