AAT1156中文资料ADJUSTABLE MULTI-CHANNEL DC-DC CONVERTERS数据手册AAT规格书

描述 Description

\tThe AAT1156 adjustable multi-channel DC-DC converter with a 2A current limit supply has both a positive and negative regulated voltage. The positive output normally supplies +18V, the inverter delivers –18V while input voltage operating at 2.8V to 5.5V. Both converters operate at 1.2MHz switching frequency to reduce external component size. It also comprises the VGH regulation and VGL regulation for the use of panel systems.


\tOther features include short circuit protect, under voltage protect, and power good control function.
