Demonstration circuit 2230A-B features the LTM4636-1EY, a 40A high efficiency, switch mode step-down power μModule® regulator with overtemperature and input/output overvoltage protection. The input voltage range is from 4.7V to 15V. For a 4.7V to 5.5V input voltage range, short PVCC pin to the VIN pin with R8 = R21 = 0Ω and remove R17. The output voltage range is 0.6V to 3.3V. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. The board operates in continuous conduction mode with heavy load conditions. For high efficiency at low load currents, the MODE_PLLIN jumper selects pulse-skipping mode for noise sensitive applications or Burst Mode® operation in less noise sensitive applications. The MODE_PLLIN pin also allows the LTM463-16 to synchronize to an external clock signal. DC2230A-B has the option of choosing either internal or external compensation circuit for the LTM4636-1. Tying the PHASMD pin to a different voltage generates a certain phase difference between the MODE_PLLIN and CLKOUT pins. The LTM4636-1 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2230A-B.
