2 ch DC/DC Converter IC Built-in Switching FET &  
voltagedetectionfunction,PFM/PWMSynchronous  
Rectification, and Down Conversion Support  
MB39C007  
DESCRIPTION  
The MB39C007 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,  
PFM/PWM control circuit, reference voltage source, and voltage detection circuit.  
External inductor and decoupling capacitor are needed only for the external component.  
MB39C007 is small, achieve a highly effective DC/DC converter in the full load range, this is suitable as the built-  
in power supply for handheld equipment such as mobile phone/PDA, DVDs, and HDDs.
