Product Details
The 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. See the Performance Summary and the LTM4712 data sheet.
The EVAL-LTM4712-A2Z has an optional constant-current feature to deliver a precise, regulated current while the load may vary.
The EVAL-LTM4712-A2Z 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 16mm × 16mm × 8.34mm ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The µModule package features an inductor on top of the molded substrate for improved heatsinking capability.
The LTM4712 data sheet gives a complete description of the device, including operation and application information. The data sheet must be read in conjunction with this evaluation board manual prior to working on or modifying the EVAL-LTM4712-A2Z evaluation board.
