1 ch DC/DC Converter IC Built-in Switching FET &
POWERGOOD function, PFM/PWM Synchronous
Rectification, and Down Conversion Support
MB39C006A
DESCRIPTION
The MB39C006A 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,
PFM/PWM control circuit, reference voltage source, and POWERGOOD circuit.
External inductor and decoupling capacitor are needed only for the external component.
MB39C006A 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.
