Product Summary
The MB3813APFV-G-BND-E is a pulse width modulation (PWM) DC/DC converter IC 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.
