SIX-CHANNEL DIGITAL STILL CAMERA POWER SUPPLY

FEATURES

GENERAL DESCRIPTION

The AAT1403A provides an integrated six-channel

z Complete PWM Power Control Circuitry

z Input Voltage Range: 1.4V to 6.5V

z Low Start-Up Voltage: 1.4V (CH6)

z Separate On/Off Control for CH1~CH6

z Supports Synchronous Boost Rectification (CH6)

z Supports Synchronous Buck Rectification (CH1, 5)

z Supports Boost Conversion (CH2, 4)

z Supports White LED Driver (CH4)

z Supports Inverting Conversion (CH3)

z Totem Pole Output

pulse-width-modulation (PWM) solution for the power

supply of DC-DC converter; this device offers system

engineer flexibility to tailor-make the power supply

circuitry for specific applications. Each channel

contains its own error amplifier, PWM comparator,

dead-time control and output driver. The under-voltage

protection, oscillator, short circuit protection and

voltage reference circuit are the common features for

the six channels.

In addition to two boost conversions and one inverting

conversion, AAT1403A also has three synchronous

rectifiers.

z Short Circuit Protection

z VQFN40 and LQFP48 Package

z Oscillator Frequency: 500 kHz (±15%)

APPLICATIONS

z Digital Cameras

z CCD Imaging Devices

z Camcorders
