General Description
The AAT3119 is a general purpose high efficiency
voltage regulated charge pump IC that can produce
output current levels up to 150mA. As a voltage
regulated output device, it may be used for general
voltage boost applications or to power white, RGB,
or flash type LEDs from a 2.7V to 5.5V input.
The voltage doubling charge pump architecture of
the AAT3119 provides for a low external part count;
just three small ceramic capacitors are needed.
This makes the AAT3119 ideally suited for small
battery-powered applications. This device oper-
ates from a fixed high frequency 1.2MHz oscillator
which enables the use of very small external
capacitors, one 1
μ
F flying capacitor, and two 1
μ
F
bypass capacitors at IN and OUT.
The AAT3119 has built-in soft-start circuitry which
prevents excessive inrush current from the source
supply during startup. A low-current shutdown fea-
ture disconnects the load from V
IN
and reduces
quiescent current to less than 1.0
μ
A when the
device is disabled. The AAT3119 is available in a
Pb-free, 8-pin SC70JW package and is rated over
the -40°C to +85°C temperature range.
