MB39C015
2ch DC/DC Converter IC Datasheet
The MB39C015 is a current mode type 2-channel DC/DC converter IC built-in voltage detection, synchronous rectifier, and down
conversion support. The device is integrated with a switching FET, oscillator, error amplifier, PWM control circuit, reference voltage
source, and voltage detection circuit.
External inductor and decoupling capacitor are needed only for the external component.
As combining with external parts enables a DC/DC converter with a compact and high load response characteristic, this is suitable
as the built-in power supply for such as mobile phone/PDA, DVDs, and HDDs.
