GENERAL DESCRIPTION

The

5-channel pulse-width-modulation (PWM) solution and

a low noise LDO for the power supply of DC-DC

converter. This device improves performance and size

compared to conventional controllers in battery design.

The AAT1415/AAT1415A has three current mode

PWM converters (CH1, CH2, and CH3) and two

voltage mode PWM converters (CH4 and CH5). Each

current-mode channel has on-chip synchronous power

FETs. The five channels include:

CH1: Boost /buck selectable DC-DC converter, which

activates PWM function at 1.2V when it is configured

as a boost converter.

CH3: Buck DC-DC converter.

CH4: Boost DC-DC controller for the CCD positive

bias.

CH5: Inverting DC-DC controller for the CCD negative

bias.

PIN CONFIGURATION

CH2: Boost / buck selectable DC-DC converter.
