About This Product

■Summary

The MPQ7235-AEC1 is a high frequency, synchronous, rectified, step-down switch-mode LED driver with integrated power MOSFETs. It is a compact solution capable of delivering up to 1.5A continuous LED current (ILED) and up to 3A peak current (IPEAK) with excellent load and line regulation over a wide input voltage (VIN) range The device offers synchronous rectification mode to obtain high efficiency. It also supports low pulse width modulation (PWM) dimming frequencies with small dimming duty cycles. The MPQ7235-AEC1 supports PWM dimming frequencies as low as 10Hz to tune infrared (IR) for LED driver applications. It supports dimming of 30fps, 60fps, and 120fps. Current mode control provides fast transient response and facilitates loop stabilization. Complete protection features include transient current protection (OCP) and thermal shutdown. The MPQ7235-AEC1 requires a minimal number of standard, readily available external components. It is available in a space-saving QFN-13 (2.5mm x 3mm) package and is AEC-Q100 qualified. Built for a wide range of infrared (IR) LED applications ・Wide 4V to 36V operating input voltage (VIN) range ・Continuous LED current (ILED) up to 1.5A ・Up to 3A peak LED current with small duty cycle and low dimming frequency (IPEAK) ・Pulse width modulation (PWM) dimming frequency from 10Hz to 2kHz ・Supports dimming of 30fps, 60fps, 120fps

■Optimized for EMC and EMI reduction

・Default switching frequency (fSW) of 2.2MHz ・EMI reduction technology

■High performance that improves thermal function

・85mΩ / 50mΩ low RDS (ON) internal power MOSFET ・0.2V reference voltage (VREF) ・Synchronous mode for high efficiency

■Abundant protection functions

・LED short circuit and LED open failure indication ・Overcurrent protection (OCP) by valley current detection ・Thermal shutdown
