The LTM4656 is a complete high efficiency boost μModule® (power module) regulator with the switching controller, power FETs, inductor, and all supporting components. Only a few input and output capacitors are needed. Operating over an input voltage range of 4.5V to 28V, the LTM4656 supports an output voltage range of 6V to 36V, set by a single external resistor. Its high efficiency design delivers up to 5A continuous output current. An in-line protection circuit sets the maximum input current, and will trip off the input power if exceeded and retry (see Typical Applications section on data sheet).

The high density boost design can convert up to 180W of output power.

Fault protection features include overtemperature protection, and overcurrent protection input referred with auto-retry. The μmodule is offered in a space saving and thermally enhanced 16mm × 16mm × 7.07mm BGA package. The LTM4656 is Pb-free and RoHS compliant.

Product Detail

Demonstration circuit 2634A is a boost µModule regulator featuring the LTM4656. The DC2634A operates from 6V to 36V input and generates 24V, 4A output from 12V input. When VIN ≥24V, VOUT follows VIN. Also, the LTM4656 has precision voltage reference, which can generate out-put voltage with 2% tolerance over the full operating conditions. The 400kHz switching frequency operation results in small and efficient circuit. The converter achieves over 95% efficiency with 4A load. The LTM4656 protects the load with the integrated soft-start and output short-circuit protection functions. The demonstration circuit can be easily modified to regulate different output voltages.

The DC2634A has small circuit footprint. It is a high performance and cost-effective solution for generating out-put voltages up to 36V from inputs as low as 5V.
