MB39A214A - 2ch DC/DC converter IC

Description

MB39A214A is a N-ch/ N-ch synchronous rectification type 2ch Buck DC/DC converter IC equipped with a bottom detection comparator for low output voltage ripple.

It supports low on-duty operation to allow stable output of low voltages when there is a large difference between input and output voltages.

Features

  • S y High efficiency y Frequency setting by internal preset function : 310 kHz, 620 kHz, 1 MHz y High accuracy reference voltage : ± 0.7% (Ta = + 25 °C) y VIN Input voltage ran.
