Renesas Electronics RAA212422 Synchronous Buck Regulators
Renesas Electronics RAA212422 Synchronous Buck Regulators are dual output regulators designed to combine 1.1A buck regulator with 1.5A buck regulator, both having different input range. These buck regulators provide an easy to use, high-efficiency, and low BOM count solution as both regulators have integrated high-side and low-side MOSFETs. The RAA212422 buck regulators feature thermal shutdown, internal and external compensation, power-good functions, hiccup overcurrent protection, and programmable soft-start. The wide VIN buck regulator switches at a frequency of 500kHz and the low VIN buck regulator operates at a switching frequency of 1MHz.
Features
Wide VIN buck regulator:3V to 40V input voltage with 1.1A output current500kHz internal fixed frequency or 300kHz to 2MHz adjustable switching frequencyInternal or external soft-startLow VIN buck regulator:2.7V to 5.5V input voltage with 1.5A output currentVOUT range: 0.6V to VIN1MHz fixed switching frequency
