Description

The AAT1343 provides an integrated two-channel pulse-width-modulation (PWM) solution for the power supply of DC-DC system; this device offers the systems engineer flexibility to tailor-make the power supply circuitry for specific applications.

Each channel contains its own error amplifier, PWM comparator, deadtime control (DTC) and output driver. The under-voltage protection, oscillator, short circuit protection and voltage reference circuit are the common features for these two channels.

Both channels of AAT1343 can be used for DC-DC converter operations including step-up, step-down, and inverting. Dead-time control can be set to provide 0% to 100% dead-time through a resistive divider network. Soft-start can be implemented by paralleling the DTC resistor with a capacitor. Two dead-time control inputs are assigned for channel 1 (CH1) and channel 2 (CH2) individually, and dead-time control inputs can be used to control on / off operation.

With a minimal number of external components, the AAT1343 offers a simple and cost effective solution.
