■ DESCRIPTION
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.
■ FEATURES
Power supply voltage range : 2.5 V to 5.5 V
For Buck DC/DC included SW FET (CH1) : output 0.8 V to 4.5 V, 600 mA Max DC
For LDO (CH2) : output 3.30 V (MB39C022G) 300
