GENERAL DESCRIPTION
The AAT1102 is a step-up DC-DC converter with
a 1.6A,
external compensation pin, this device offers user
flexibility in determining loop dynamic and
adjusting operating frequency. AAT1102 also
allows the use of small, low equivalent resistance
(ESR) ceramic output capacitor, and it’s capable
of converting a standard input of 3.3V to multiple
outputs of 8V,
filtering and loop performance are facilitated and
enhanced by a high switching frequency of either
640 kHz or1.3MHz.
The
power-smart design.
with an external capacitor that sets the input
current
consumption to
operating, a mere 2.6V input yields an impressive
output voltage as high as 15V.
High switching frequency and economical design
allow AAT1102 to be less than 1.1mm high. Its
compact 8-pin MSOP package and superior
performance make it an ideal part for biasing TFT
displays.
