AAT1100 General Description

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 comparator, dead-time control (DTC) and output driver. The under-voltage protection, oscillator, short circuit protection and voltage reference circuit are common features of the three channels.

The AAT1100 contains two boost circuits (CH1, CH3) and a buck-boost circuit (CH2). DTC can be set to provide 0% to 100% dead-time through a divider network. Soft-Start can be implemented by paralleling the DTC resistor with a capacitor. Two DTC inputs are assigned for CH1, CH3 pair and CH2 individually, and DTC inputs can be used to control on / off operation. In addition, this device can operate from 2.5V to 7.0V supply voltages to achieve efficient operation in low power system. With a minimal number of external components, the AAT1100 offers a simple and cost effective solution.
