General Description
The AAT1104/AAT1104A 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.
Both channel of AAT1104/AAT1104A can be used
for DC/DC converter operations including step-up,
step-down, and inverting. 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 AAT1104/AAT1104A offers a simple and cost
effective solution.
