DESCRIPTION
The FUJITSU MB3871 is a pulse width modulation (PWM) DC/DC converter IC chip that provides a selection of
1.3 V to 2.0 V output voltages for Mobile Pentium
II* CPU’s, using a 4-bit input signal information.
The MB3871 utilizes synchronous rectification for high efficiency and features a soft-start/discharge control
function for ease in designing power supplies in multi-supply systems, making it ideal for Mobile Pentium
II power
supply systems.
