MB39C022J
Description
Buck DC/DC Converter + Low Noise LDO
The MB39C022 is a 2 channels power supply IC. It consists of one channel Buck DC/DC Converter and one channel LDO regulator. The DC/DC converter has fast transient response with current mode control topology. Moreover, the integrated LDO provides an auxiliary output supply for noise sensitive circuit.
