DESCRIPTION
The MB39A112 is a 3-channel DC/DC converter IC using pulse width modulation (PWM) , and the MB39A112 is
suitable for down-conversion.
3-channel is built in TSSOP-20P package. Each channel can be controlled and soft-start.
The MB39A112 contains a constant voltage bias circuit for output block, capable of implementing an efficient
high-frequency DC/DC converter. It is ideal for built-in power supply such as ADSL modems.
