DC1743A

DC1743A is a LTM4613 8A, high voltage power µModule regulator demonstration board. Demonstration circuit DC1743A features the LTM®4613EV, an EN55022 class B certified, high input and output voltage, high efficiency, switch mode step-down power µModule® regulator. The input voltage range is from 5V to 36V. The output voltage is jumper programmable from 3.3V to 12V with a rated load current of 8A. The DC1743A offers the TRACK/SS pin allowing the user to program output tracking or soft-start period. Output voltage margining can also be realized through jumper position selections. Higher efficiency at low load currents is achieved by setting the MODE pin jumper to DCM. The PLL pin is available to synchronize the LTM4613EV to an external clock.

• 600KHz default operating frequency at VOUT = 12V
• 93% efficiency at VIN = 12V, VOUT = 5V, IOUT = 8A
