Description	TRIPLE-CHANNEL PWM CONTROLLER
Datasheet	AAT1100_AdvancedAnalogicTechnologies.pdf

The AAT1100 provides an integrated triple-channel pulse-width-modulation (PWM) solution for the power supply of DC-DC system;

this device offers system engineer the flexibility to custom-make the power supply circuitry to a specific application.

Each channel contains its own error amplifier, PWM parator, dead–time control (DTC) and output driver.
