General Description
The AAT1106 series provides an integrated
two-channel pulse-width-modulation (PWM)
solution for the power supply of DC-DC system,
this device offers the systems engineer the
flexibility to tailor the power supply circuitry to a
specific application. Each channel contains its own
error amplifier, PWM comparator, dead–time
control and output driver. The under-voltage
protection, oscillator, short circuit protection and
voltage reference circuit are common for the two
channels.
The AAT1106 contains two boost (step-up)
exclusive circuit. Dead-time control (DTC) can be
set to provide 0% to 100% dead time by resistive
divider network. Soft start can be implemented by
paralleling the DTC resistor with a capacitor. Two
dead time control inputs are assigned for Ch-1 and
Ch-2 individually, and dead time control inputs can
be used to control on / off operation.
With a minimum number of external components,
the AAT1106 series offers a simple and cost
effective solution.
