FAN65005A

Voltage Regulators - DC DC Switching Regulators Overview

The FAN65005A is a high-performance, multi-mode power factor correction (PFC) controller designed for universal input AC-DC applications. It integrates an interleaved boundary conduction mode (iBCM) PFC stage with a synchronous rectification (SR) flyback converter. The device supports up to 150W output power and features adaptive valley switching for reduced switching losses. Key electrical parameters include a wide operating voltage range from 85VAC to 265VAC, a fixed switching frequency of 65kHz for the PFC stage, and a programmable switching frequency for the SR flyback stage ranging from 40kHz to 130kHz. It operates with a supply voltage range of 9V to 30V.
