MB39A108 - Fujitsu

MB39A108 5-Channel DC/DC Converter

The MB39A108 is 5-channel DC/DC converter IC using pulse width modulation (PWM), and is suitable for up conversion, down conversion, and up/down conversion. The MB39A108 is built in 5 channels into TSSOP-38P/ BCC-40P package and operates at 2 MHz maximum. Each channel can be controlled with soft-start. The MB39A108 is suitable for power supply of high perfor.
