Description
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 applications. Both regulators feature internal and external compensation, thermal shutdown, and power-good functions. The wide VIN buck regulator 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 overcurrent protection. The low VIN buck regulator operates at 1MHz switching frequency, which provides fast load transient response allowing the use of small inductors. Because the high-side MOSFET of the low VIN buck regulator is a PMOS, a boot capacitor is not needed, reducing the external component count. They operate at 100% duty cycle and in PWM mode only, reducing noise susceptibility and RF interference. The RAA212422 is available in a small RoHS compliant 3mmx6mm TDFN plastic package with a full-range industrial temperature of -40°C to +125°C.
