AAT1100 Datasheet PDF - Advanced Analogic Technologies

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.
