GENERAL DESCRIPTION
The AAT1109 is a one-channel step-up PWM
controller incorporating a soft-start and a short
circuit protection (SCP) function.
This device consists of an on-chip voltage reference,
error amplifier, pulse width modulation controller,
under-voltage lockout protection, soft-start, and
short
frequency up to 1MHz is set by an external resistor
and capacitor. Soft-start time can be implemented
by the SCP capacitor.
Additionally, a chip-enable feature is also provided
to power down and reduce the current supply

... CIRCUIT PROTECTION 1. Soft-Start AAT1109 operates in soft-start mode. The PWM comparator monitors the voltage at soft-start setting and SCP pin, which varies proportionally to each other. This proportion relation controls the ON duty of the OUT pin and activates the soft-start operation. In the Soft-start mode, the voltage at SCP pin ...
