The LTM4615 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. The LTM4615 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 (2.82mm) enables utilization of unused space on the bottom of PC boards for high density point of load regulation. High switching frequency and a current mode architecture enables a very fast transient response to line and load changes without sacrificing stability. The device supports output voltage tracking for supply rail sequencing. Additional features include overvoltage protection, foldback overcurrent protection, thermal shutdown and programmable soft-start. The power module is offered in a space saving and thermally enhanced 15mm × 15mm × 2.82mm LGA package. The LTM4615 is Pb-free and RoHS compliant.

Demonstration circuit 1367A features the LTM®4615EV, a triple output μModule® regulator consisting of two switch mode outputs and one LDO output. Each LTM4615 DC/DC converter has a separate input and enable pin. The LTM4615 maximum load current is 4A for each switch mode channel and 1.5A for the VLDO™ channel. However the DC1367A is configured with the LDO input supply connected to the VOUT2 whose maximum output current decreases accordingly. Derating is necessary for certain VIN, VOUT PERFORMANCE SUMMARY and thermal conditions. The LTM4615 data sheet must be read in conjunction with this manual prior to working on or modifying DC1367A.
