Product Details
The EVAL-LTM4712-A1Z evaluation board is a power supply generating 12V, 24A (max) from a 5V to 36V input. The EVAL-LTM4712-A1Z is a dual-phase solution featuring the LTM4712, a high-efficiency, buck-boost μModule® (micromodule) regulator. The EVAL-LTM4712-A1Z is capable of 24A in buck and buck-boost modes and 12A in boost mode. Derating is necessary for certain VIN, VOUT, frequency, and thermal conditions. See the Performance Summary section and the LTM4712 data sheet for more information.
The EVAL-LTM4712-A1Z evaluation board has an optional constant-current feature to deliver a precise, regulated current while the load may vary.
The EVAL-LTM4712-A1Z evaluation board 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 user guide prior to working on or modifying the EVAL-LTM4712-A1Z evaluation board.
