MB39A103

FUJITSU MB39A103 has emphasized the development of power supply ICs for high-performance portable devices such as digital still cameras, and have developed products MB3785A/MB3825A/MB3827/MB3881/MB3883/MB39A 102. And now it has developed a 4-channel DC/DC converter IC, MB39A103, which is optimal for use in built-in multipurpose power supply systems used in high-performance portable devices.


The MB39A103 is a pulse width modulation type (PWM method) 4-channel DC/DC converter IC which is suitable for up conversion, down conversion and up / down conversion. Achievement of low voltage startup (1.7V􀊙) enables operation from a low voltage. With 4 built-in channels in TSSOP-30P/BCC-32P package, control and soft-start on each channel is possible. Furthermore, a soft-start circuit and a timer latch type short-circuit detection circuit are built in to prevent inrush current when power is turned on and overcurrent at output short-circuit. The MB39A103 is an optimal power supply for high function, portable devices such as digital still cameras.
