Analog Devices LTM4683 | Demoboard EVAL-LTM4683-A2Z

Beschreibung

The EVAL-LTM4683-A2Z evaluation board features the LTM4683: the wide input and output voltage range, high efficiency and power density, quad output PolyPhase® DC-to-DC step-down µModule® (micromodule) regulator with digital power system management (PSM). The EVAL-LTM4683-A2Z evaluation board is configured as a 4-phase single output. A similar evaluation board with a 4- phase four outputs is also available (EVAL-LTM4683-A1Z).The EVAL-LTM4683-A2Z evaluation board’s default input voltage range is 4.5V to 14V. However, if VIN is lower than 6V and within 4.5V ≤ VIN ≤ 5.75V, a minor modification to certain existing on-board components is required.
