RT5752
Description
The RT5752 is a simple, easy-to-use, 2A synchronous step-down DC-DC converter with an input supply voltage range from 2.5V to 6V. The device builds in an accurate 0.6V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in TSOT-23-5, TSOT-23-6 and WDFN-6L 2x2 packages.
The RT5752 adopts Advanced Constant On-Time (ACOT®) control architecture to provide an ultrafast transient response with few external ponents and to operate in nearly constant switching frequency over the line, load, and output voltage range. The RT5752A operates in automatic PSM that maintains high efficiency during light load operation. The RT5752B operates in Forced PWM that helps to meet tight voltage regulation accuracy requirements.
The RT5752 senses both FETs current for a robust overcurrent protection. The device features cycle-by-cycle current limit protection which prevents the device from the catastrophic damage in output short circuit, over current or inductor...
