General Description
The AAT1109A is a one-channel switching
regulator control IC incorporating a soft start
function and a short circuit protection function.
Each device consists of an on-chip voltage reference,
error amplifier, pulse width modulation controller,
under-voltage protection, soft start and short circuit
protection circuits. Switching frequencies up to
1MHz are set by an external resistor and capacitor.
Soft-start time can be implemented by the SCP
capacitor.
Additionally, a chip enable feature is provided to
power down reducing the supply current to 10uA.
With a minimum number of external components,
the AAT1109A offers a simple and cost effective
solution.
