| Advanced Analog Technology, Inc. AAT1403B Details are subject to change without notice SIX-CHANNEL DIGITAL STILL CAMERA POWER SUPPLY FEATURES Complete PWM Power Control Circuitry Input Voltage Range: 1.4V to 6.5V Low Start-Up Voltage: 1.4V (CH6) Separate On/Off Control for CH1~CH6 Supports Synchronous Boost Rectification (CH1,6) Supports Synchronous Buck Rectification (CH5) Supports Boost Conversion (CH2, 4) Supports White LED Driver (CH4) Supports Inverting Conversion (CH3) Totem Pole Output Short Circuit Protection VQFN40 and LQFP48 Package Oscillator Frequency: 500 kHz (15%) GENERAL DESCRIPTION The AAT1403B provides an integrated six-channel 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, AAT1403B also has three synchronous rectifiers.
