Advanced Analog Technology, Inc. AAT1 102 (BIN2) Product information presented is current as of publication date. Details are subject to change without notice ADVANCED PWM DC-DC CONVERTER WITH INTERNAL SWITCH AND SOFT-START FEATURES GENERAL DESCRIPTION 1.6A, 0.23Ω, Internal Switch High Efficiency: 90% The AAT1102 is a step-up DC-DC converter with Adjustable Output: V to 15V a 1.6A, 0.23Ωinternal switch. Equipped with an DD external compensation pin, this device offers user Adjustable Frequency: 640kHz or 1.3MHz flexibility in determining loop dynamic and Wide Input Range: +2.6V to +5.5V adjusting operating frequency. AAT1102 also Low Shutdown Current: 0.1μA allows the use of small, low equivalent resistance Programmable Soft-Start (ESR) ceramic output capacitor, and it’s capable Small 8-Pin MSOP Package of converting a standard input of 3.3V to multiple outputs of 8V, −8V , and 23V. Furthermore, filtering and loop performance are facilitated and enhanced by a high switching frequency of either 640 kHz or1.3MHz. PIN CONFIGURATION TOP VIEW
