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.

High speed for input and load transient response in the current mode
Over temperature protection
Packaged in a compact package
: SON10
Applications
Flash ROMs
MP3 players
Electronic dictionary devices
Surveillance cameras
Portable GPS navigators
Mobile phones etc.
