■ DESCRIPTION

The MB39A105 is 1-channel DC/DC converter IC using pulse width modulation (PWM). This IC is ideal for up conversion.

The minimum operating voltage is low (1.8 V) , and the MB39A105 is best for built-in power supply such as LCD monitors. Also the short-circuit protection detection output function prevents input/output short on a chopper type up-converter.

This product is covered by US Patent Number 6,147,477.
