■DESCRIPTION
The MB39A110 is a 4-channel DC/DC converter IC using pulse width modulation (PWM). This IC is ideal for up
conversion, down conversion, and up/down conversion.
This is built-in 4 ch in TSSOP-38P package and operates at 2 MHz Max. Each channel can be controlled, and
soft-start.
This is an ideal power supply for high-performance portable devices such as digital still cameras.
This product is covered by US Patent Number 6,147,477.
