GENERAL DESCRIPTION

The AAT1102 is a step-up DC-DC converter with

a 1.6A,

0.23

惟

internal switch. Equipped with an

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鈥檚 capable

of converting a standard input of 3.3V to multiple

outputs of 8V,

鈭?/div>

, and 23V. Furthermore,

filtering and loop performance are facilitated and

enhanced by a high switching frequency of either

640 kHz or1.3MHz.

The AAT1102鈥檚 versatility comes with a

power-smart design. A soft-start programmed

with an external capacitor that sets the input

current ramp rate, reduces the current

consumption to

0.1

渭

in shutdown mode. When

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.
