MB39A104 - 2-Channel DC/DC Converter IC

Datasheet Summary

Description

The MB39A104 is a 2-channel DC/DC converter IC using pulse width modulation (PWM), incorporating an overcurrent protection circuit (requiring no current sense resistor).

This IC is ideal for down conversion.

Operating at high frequency reduces the value of coil.

Features

  • Built-in timer-latch overcurrent protection circuit (requiring no current sense resistor) Power supply voltage range : 7 V to 19 V Reference voltage : 5.0 V ± 1 % Error amplifier threshold voltage : 1.24 V ± 1 % High-frequency operation capability : 1.5 MHz (Max) Built-in standby function: 0 µA (Typ) Built-in soft-start circuit independent of loads Built-in totem-pole type output for Pch MOS FET s.
