RAA212422 synchronous buck regulator

DATASHEET RAA212422 Dual channel 40V 1.1A and 5.5V 1.5A synchronous buck regulators FN9326 Rev.2.00 Feb 27, 2020 The RAA212422 is a dual output regulator combining a 1.1A synchronous buck regulator with an input range of 3V to 40V with a 1.5A synchronous buck regulator with an input voltage range of 2.7V to 5.5V. Because both high-side and low-side MOSFETs are integrated for both regulators, the RAA212422 provides an easy-to-use, high-efficiency, and low BOM-count solution for a variety of ap.

RAA212422 Features

* a PFM mode for improved efficiency at light load. This feature can be disabled if forced PWM mode is desired. It switches at a default frequency of 500kHz; however, it can also be programmed using an external resistor from 300kHz to 2MHz. Other features include programmable soft-start and hiccup ove
