■ DESCRIPTION
The MB3832A is a pulse width modulation (PWM) DC/DC converter IC, incorporating a current detector amplifier and error amplifiers (2 circuits) to control the output voltage and current independently. It is suitable for downconversion.
With an on-chip reference voltage generator, the MB3832A is best suited for use in applications such as lithiumion battery (1-cell to 3-cell) chargers.
