Analog Devices LTM4712 | Demoboard DC3189A

Beschreibung

Demonstration circuit 3189A features the LTM4712, a high efficiency, buck-boost μModule® regulator with a 5V to 36V input voltage range and 1V to 36V output voltage range. The output is capable of 12A in buck and buck-boost modes, and 6A under 12VIN and 24VOUT. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. For more information, see the LTM4712 data sheet.The DC3189A demo board features a constant-current mode (CCM) to deliver a precise, regulated current while the load may vary.The DC3189A demo board is optimized using a default frequency of 400kHz. The current mode architecture used in the LTM4712 is peak-current mode control. The LTM4712 operates in continuous current mode by default but can be placed in pulse-skipping mode to optimize efficiency at light loads.
