LTM4615EV#PBF

LTM4615 is a triple output, low voltage DC/DC µModule regulator. It is a complete 4A dual output switching mode DC/DC power supply plus an additional 1.5A VLDO (very low dropout) linear regulator. Included in the package are the switching controllers, power FETs, inductors, a 1.5A regulator and all support components. The dual 4A DC/DC converters operate over an input voltage range of 2.375V to 5.5V, and the VLDO operates from a 1.14V to 3.5V input. It supports output voltages ranging from 0.8V to 5V for the DC/DC converters, and 0.4V to 2.6V for the VLDO. The three regulator output voltages are set by a single resistor for each output. Only bulk input and output capacitors are needed to complete the design. The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation. It is used in application such as telecom and networking equipment, industrial power systems, low noise applications, FPGA, SERDES power etc.
