Datasheet
The PM8903 is a compact, high-efficiency, monolithic step-down switching voltage regulator which can deliver up to 3 A of continuous current. The IC minimizes external components and board space by incorporating low-resistance MOSFETs into the IC. It is used in applications including CPU, DSP and FPGA power supplies, distributed power supplies, and for general DC/DC converters. The PM8903 features an input voltage range of 2.8 V to 6 V, adjustable output voltage to as low as 0.6 V, PSKIP mode for optimizing efficiency at light load, undervoltage, overvoltage, overcurrent, and overtemperature protection, power good output, 1.1 MHz switching frequency which enables the use of a small inductor, low quiescent current when shut down (<15 µA), interleaving synchronization (up to two ICs), and a small VFQFPN16, 3x3 mm package.
