LTM4628IY

开关稳压器 [Tin-Lead SnPb BGA] Dual 8A or Single 16A DC/DC uModule Regulator

DESCRIPTION

The LTM®4628 is a complete dual 8A output switching mode DC/DC power supply and can be easily configured to provide a single 2-phase 16A output. Included in the packagearetheswitchingcontroller, powerFETs, inductor, and all supporting components. Operating from an input voltage range of 4.5V to 26.5V, the LTM4628 supports two outputs each with an output voltage range of 0.6V to 5.5V, set by a single external resistor. Its high efficiency design delivers 8A continuous current for each output. Only a few input and output capacitors are needed.
