AAT1102A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

\tThe AAT1102A is a step-up DC-DC converter with a current mode boost regulator which provides a fast transient response supply voltage. It provides an output voltage up to 16V from input voltages ranging from 2.6V to 5.5V. The boost regulator integrates a low RDSON (0.23Ω) N-MOSFET, and operates at a selectable switching frequency of either 640kHz or 1.3MHz, thereby minimizing board space while providing good efficiency. An externally programmed soft start minimizes inrush current and output overshoot. In shutdown mode, current consumption is reduced to 0.1μA.


\tHigh switching frequency and economical design allows AAT1102A to be less than 1.1mm high. Its compact 8-pin MSOP package and superior performance makes it an ideal part for biasing TFT displays. The device is rated to operate from –40°C to +85°C ambient temperature range.
