MB39A103 - 4-Channel DC/DC Converter IC

Datasheet Summary

Description

The MB39A103 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.

Achievement of low voltage start-up (1.7 V or more) enables operation from low voltage.

Features

  • S.
  • Supports for down-conversion and up/down Zeta conversion (CH1) Supports for up-conversion and up/down Sepic conversion (CH2 to CH4) Low voltage start-up (CH4): 1.7 V Power supply voltage range : 2.5 V to 11 V Reference voltage : 2.0 V ± 1 % Error amplifier threshold voltage : 1.24 V ± 1.5 % Built-in totem-pole type output for MOS FET Built-in soft-start circuit independent of loads High-frequenc.
