MB39C014 1 ch DC/DC Converter IC with PFM/PWM Synchronous Rectification 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 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. Features ■ High efficiency : 96% (Max) ■ Output current (DC/DC) : 800 mA (Max) ■ Input voltage range : 2.5 V to 5.
