MAP3524 datasheet – Quasi-Resonant Mode Buck Controller for LED Backlight
Datasheet Version 1.1
MAP3524
2-CH Quasi-Resonant Mode Buck Controller for LED Backlight
General Description
Features
MAP3524 is a 2 channel quasi-resonant mode buck controller for LED backlight application. It operates at boundary conduction mode which provides better efficiency and lower EMI.
MAP3524 features ±2% current sensing(CS) voltage accuracy and has dedicated Independent analog dimming input up to 3.3V. It can be powered from 8.5V ~ 18V supply.
MAP3524 provides MOSFET drain-source short detection for fault output, VCC over voltage protection (OVP) detection for fault output, current sense resistor short protection, short circuit protection (SCP) and VCC under voltage lockout (UVLO).
