MB3813A - Lithium Ion Battery Charger DC/DC Converter

Datasheet Summary

Description

The FUJITSU MB3813A/33A/43 are pulse width modulation (PWM) DC/DC converter ICs with independent output voltage and current setting capability.

The use of on-chip output setting resistance enables high precision output voltage control.

Features

  • Output setting resistance is on-chip for high precision output voltage: ±1.0% SEL pin enables output voltage selection High precision reference voltage source: 2.5 V ± 1.0% High frequency operating capability: max. 500 kHz On-chip current detector amplifier with wide in-phase input voltage range: 0 V to VCC (Continued) s.
