EVAL-LTM4712-A2Z

EVAL-LTM4712-A2Z evaluation board is a power supply generating 12V, 48A (max) from a 5V to 36V input. It is a quad PolyPhase® solution featuring the LTM4712, a high-efficiency, buck-boost µModule® (micromodule) regulator. The EVAL-LTM4712-A2Z is capable of 48A in buck and buck-boost modes and 24A in boost mode. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. The EVAL-LTM4712-A2Z has an optional constant-current feature to deliver a precise, regulated current while the load may vary. It is optimized using a default frequency of 400KHz. The peak current mode control architecture allows easy current sharing. The LTM4712 operates in continuous current mode by default but can be placed in pulse-skipping mode to optimize efficiency at light loads. The LTM4712 is offered in a BGA package suitable for automated assembly by standard surface mount equipment. The µModule package features an inductor on top of moulded substrate for improved heatsinking capability.
