Description

The MB39A104 is a 2-channel DC/DC converter IC using pulse width modulation (PWM), incorporating an overcurrent protection circuit (requiring no current sense resistor). This IC is ideal for down conversion.

Operating at high frequency reduces the value of coil.

The MB39A104 is ideal for built-in power supply such as LCD monitors and ADSL.

The MB39A104 is covered by US Patent Number 6,147,477.
