MAP3511 - Average Current Control Buck Controller

General Description

MAP3511 is an 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 highside 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. MAP3511 provides MOSFET DS short detection(FLT output), SCP and UVLO. MAP3511 is available 8 leads SOIC with Halogenfree (fully RoHS compliant). Features  8.5V to 18V Input Voltage Range  Average-Mode Current Control  Programmable Constant off-time  Up to 3V Analog Dimming Input  1% CS Voltage Accuracy  Direct PWM Dimming Input  Fault Output(MOSFET Drain.
