AAT1102中文资料ADVANCED PWM DC-DC CONVERTER WITH INTERNAL SWITCH AND SOFT-START数据手册AAT规格书

描述 Description

GENERAL DESCRIPTION
The AAT1102 is a step-up DC-DC converter with a 1.6A, 0.23Ω 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’s capable 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.FEATURES
■ 1.6A, 0.23Ω, Internal Switch
