DC2989A

DC2989A is a LTM4657 20Vin, 8A step-down µModule® regulator demonstration board. Demonstration circuit 2989A features the LTM4657µModule® regulator, a high performance, high efficiency step-down regulator. The LTC®4657 is a complete DC/DC point-of-load regulator in a thermally enhanced 6.25mm x 6.25mm x 3.87mm BGA package. The LTM4657 has an operating input voltage range of 3.1V to 20V and provides an output current up to 8A. The output voltage is programmable from 0.6V to 5.5V and can be remotely sensed. The stacked inductor design improves thermal dissipation and significantly reduces the package area. Output voltage tracking is available through the TRACK/SS pin for supply rail sequencing. External clock synchronization is available through the SYNC/MODE pin. For high efficiency at low load currents, select DCM mode operation using the MODE jumper in less noise sensitive applications.

• Output voltage VOUT 1VDC, 1.5VDC, 2.5VDC, 3.3VDC, 5VDC (Jumper selectable, TA = 25°C)
• Default operating frequency of 500KHz
• 88.3% efficiency at VIN = 12V, VOUT = 1.5V, IOUT = 8A, TA = 25°C
