MB39A202A概要说明书

MB39A202A is a 2ch DC/DC buck converter IC equipped with a bottom detection comparator for low output
voltage ripple and N-ch/N-ch synchronous rectification, and built-in 2ch LDO circuits. The built-in LDO (5.0V
100mA / 3.3V 50mA）is possible to slim of the system. The DC/DC buck converter supports low on-duty
operation to allow stable output of low voltages when there is a large difference between input and output
voltages. LDO is possible to operate alone at the DC/DC standby. MB39A202A is suitable for the power
supply usage to various peripherals of Notebook PC and the built-in equipment.
