MB39A123 - 6-ch DC/DC Converter IC

Datasheet Summary

Description

MB39A123 is a 6-channel DC/DC converter IC using pulse width modulation (PWM) , and it is suitable for up conversion, down conversion, and up/down conversion.

MB39A123 is built in 6 channels into LQFP-48P package and this IC can control and soft-start at each channel.

Features

  • Supports for step-down with synchronous rectification (ch.1).
  • Supports for step-down and up/down Zeta conversion (ch.2 to ch.4).
  • Supports for step-up and up/down Sepic conversion (ch.5, ch.6).
  • Negative voltage output (Inverting amplifier) (ch.4).
  • Low voltage start-up (ch.5, ch.6) : 1.7 V.
  • Power supply voltage range : 2.5 V to 11 V.
  • Reference voltage : 2.0 V  1%.
  • Error amplifier reference voltage : 1.0 V  1% (ch.1) , 1.23 V ± 1% (ch.2 to ch.6).
  • Osc.
