DC2527A-A

DC2527A-A demonstration circuit features the LTM®4662EY, a dual 15A or single 30A high efficiency, switch mode step-down power µModule regulator. The input voltage range is from 4.5V to 20V. With CPWR bias, input voltage can be as low as 2.375V. The output voltage range is 0.6V to 5.5V. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. The DC2527A-A offers the TRACK/SS pin allowing the user to program output tracking or soft-start period. For high efficiency at low load currents, the MODE_PLLIN jumper can select discontinuous conduction mode. The MODE_PLLIN pin also allows the LTM4662 to synchronize to an external clock signal (between 250KHz and 1MHz). DC2527A-A has the option of choosing both internal and external compensation circuit for LTM4662. Tying the PHASMD pin to different pins generates certain phases of CLKOUT and Channel 2.
