8-ch DC/DC Converter IC with Synchronous
Rectifier for
Voltage Step-up and Step-down
MB3881
s DESCRIPTION
The MB3881 a step-up/step-down type of 8-channel, DC/DC converter IC.
It uses pulse width modulation (PWM) and synchronous rectification, designed for low
voltage, high efficiency, and compactness.
This IC is ideal for down conversion and up/down conversion (employing a step-up/step-down Zeta system enabling free I/O setting).
The MB3881 can use channel 8 as its own power supply to provide a wide range of supply
voltages, allowing itself to operate at low
voltage.
In addition, the MB3881 contains a ...
