General Description

Highly integrated PWM controller, FAN6861 is optimized for applications with motor load;

such as printer and scanner, which inherently impose some kind of overload condition on the power supply during acceleration mode.

The two-level OCP function allows the SMPS to stably deliver peak power during the motor acceleration mode without causing premature shutdown and while protecting the SMPS from overload condition.

Overview

FAN6861 — Low-Cost, Highly Integrated, Green-Mode PWM Controller for Peak Power Management May 2009 FAN6861 Low-Cost, Highly Integrated, Green-Mode PWM Controller for Peak Power.

Key Features

  • Low Startup Current: 15µA Maximum Green-Mode and Burst-Mode Operation for Low Standby Power Consumption Internal Soft Start: 10ms Frequency Hopping for EMI Reduction Peak-Current Mode Control with Cycle-by-Cycle Current Limiting Constant Output Power Limit (Full AC Input Range) Built-in Slope Compensation Two-Level Over-Current Protection (OCP) with Delayed Shutdown (780ms) for Peak Power Management Open-Loop / Over-Load Protectio.
