MAP3613 - 3-CH Average Current Control Buck Controller

General Description

MAP3613 is a 3 channel average-mode current control buck controller for LED backlight application.

It does not require an additional dimming MOSFET and utilizes constant off-time control and average current control feedback without external loop compensation or high-side current sensing.

Key Features

  • ±1% CS voltage accuracy and has dedicated analog dimming input up to 3V. It can be powered from 8.5V ~ 18V supply. MAP3613 provides MOSFET DS short and freewheeling diode open detection(FLT output), sense resistor short protection, SCP, ODP and UVLO. MAP3613 is available 20 leads SOIC with Halogenfree (fully RoHS compliant). Features  8.5V to 18V Input Voltage Range  Average-Mode Current Control  Programmable Constant Off-time - Independent Setting per Channel.
