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. Also, an output voltage
switching feature for use with either graphite-electrode or coke-electrode lithium-ion batteries makes this IC ideal
for internal battery chargers in notebook personal computers and similar applications.
