Product details

Description

The MB3878 is a DC/DC converter IC suitable for down-conversion, using pulse-width (PWM) charging and enabling output voltage to be set to any desired level from one cell to four cells.

Features

Detecting a voltage drop in the AC adaptor and dynamically controlling the charge current (Dynamically-controlled charging).
Output voltage setting using external resistor : 1 cell to 4 cells.
High efficiency : 94 %.
Wide range of operating supply voltages : 7 V to 25 V.
Output voltage setting accuracy : 4.2V ± 0.8% (per cell).
Built-in frequency setting capacitor enables frequency setting using external resistor only.
Oscillator fr.
