MB39C014
Description
The MB39C014 is a current mode type 1-channel DC/DC converter IC built-in switching FET, synchronous rectification, and down conversion support. The device is integrated with a switching FET, oscillator, error amplifier, PWM control circuit, reference voltage source, and POWERGOOD circuit. External inductor and decoupling capacitor are needed only for the external ponent. As bining with external parts enables a DC/DC converter with a pact and high load response characteristic, this is suitable as the built-in power supply for such as mobile phone/PDA, DVDs, and HDDs.
