LTM4620A(V2) 数据手册 ( 数据表 ) - Linear Technology

DESCRIPTION
TheLTM®4620Aisacompletedual13A, orsingle26Aoutput switchingmodeDC/DCpowersupplywithwiderVOUTrange and higher efficiency than the LTM4620. Included in the packagearetheswitchingcontroller, powerFETs, inductors and all supporting components. Operating from an input voltage range of 4.5V to 16V, the LTM4620A supports two outputs each with an output voltage range of 0.6V to 5.3V, set by a single external resistor. Its high efficiency design delivers up to 13A continuous current for each output. Only a few input and output capacitors are needed.
