DATASHEET RAA212421 3V to 40V Input, 1.1A Synchronous Buck Regulator with Integrated 500mA LDO FN9309 Rev.3.00 Jul 8, 2019 The RAA212421 is a dual-output regulator combining a 3V to 40V input, 1.1A synchronous buck converter with a 500mA LDO featuring fast transient response.

The combination of two high-performance power supplies in one compact 3x6mm package provide an easy-to-use, high-efficiency compact solution.

The wide VIN buck regulator of the RAA212421 integrates both high-side and low

RAA212421 Features

* a PFM mode for improved efficiency at light load. This feature can be disabled if forced PWM mode is desired. It can use internal or external compensation, which minimizes the required external components, reduces BOM count and complexity of design. The part switches at a default frequency of 500kHz
