Overview

MB39A112 3-ch DC/DC Converter IC The MB39A112 is a 3-channel DC/DC converter IC using pulse width modulation (PWM) , and the MB39A112 is suitable for downconversion.

3-channel is built in TSSOP-20P package.

Each channel can be controlled and soft-start.

Key Features

  • Supports for down-conversion (CH1 to CH3).
  • Power supply voltage range : 7 V to 25 V.
  • Error amplifier threshold voltage : 1.00 V ± 1% (CH1) : 1.23 V ± 1% (CH2, CH3).
  • Oscillation frequency range : 250 kHz to 2.6 MHz.
  • Built-in soft-start circuit independent of loads.
  • Built-in timer-latch short-circuit protection circuit.
  • Built-in totem-pole type output for P-channel MOS FET devices.
  • Built-in constant voltage (VCCO - 5 V) bias circuit for output bl.
