RAA808015A, RAA808015B
2.7V to 5.5V Input, 5A Synchronous Buck Regulators
Datasheet
The RAA808015A/B family (RAA808015A, RAA808015B) is a 5A synchronous buck regulator with an input range of 2.7V to 5.5V. It provides an easy-to-use, high-efficiency low BOM count solution for a variety of applications.
The RAA808015A integrates both high-side and low-side MOSFETs and features a PFM mode for improved efficiency at light loads. This feature can be disabled if forced PWM option (RAA808015B) is required.
The RAA808015A/B adopts Constant On-Time (COT) control architecture to provide an ultrafast transient response with few external components and to operate in nearly constant switching frequency over the line, load, and output voltage range. The RAA808015A switches at a default frequency of 1.
