MB3813A Lithium Ion Battery Charger DC/DC Converter

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. Also, an output voltage switching feature for use with either graphite-electrode or coke-electrode lithium-ion batteries mak.
