General Description
The AAT1103/AAT1103A is a single channel
pulse-width-modulation (PWM) controller circuit
solution for low voltage applications. A low
minimum operating voltage of 2.5V is ideal for
the power supply voltage of Li-Ion
battery-operated electronic equipment.
The IC provides soft start, short circuit protection
and shut down functions. During shut down mode,
current consumption is reduced less than 1µA. The
error amplifier gain is built in the IC, so external
components are minimized. An external
compensation pin gives user flexibility in
determining loop compensation.
