2ch DC/DC Converter IC Datasheet

The MB39C015 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, PWM control circuit, reference voltage

source, and voltage detection 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)

■ Input voltage range

■ Operating frequency

■ No flyback diode needed

■ Low dropout operation

: 800 mA/ch (Max)

: 2.5 V to 5.5 V

: 2.0 MHz (Typ)

: For 100% on duty

■ Built-in high-precision reference voltage generator : 1.30 V  2%

■ Consumption current in shutdown mode

: 1 A or less

■ Built-in switching FET

: P-ch MOS 0.3 Ω (Typ) N-ch MOS 0.2 Ω (Typ)

■ High speed for input and load transient response in the current mode

■ Over temperature protection

■ Packaged in a compact package

: QFN-24

Applications

■ Flash ROMs

■ MP3 players

■ Electronic dictionary devices

■ Surveillance cameras

■ Portable GPS navigators

■ DVD drives

■ IP phones

■ Network hubs

■ Mobile phones etc.
