Product Overview

The DC2230A-A from Linear Technology is a 40A, LTM4636EY DC to DC µModule regulator demo board. This demonstration circuit features LTM4636EY, a 40A high efficiency, switch mode step down power µModule regulator. The input voltage ranges from 4.7V to 15V. For input voltage range from 4.7V to 5.5V, short PVCC pin to VIN pin with R8 = R21 = 0 ohm and remove R17. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. The board operates in continuous conduction mode in 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 LTM4636 to synchronize to an external clock signal. DC2230A-A has the option of choosing both internal and external compensation circuit for LTM4636. Tying the PHASMD pin to different voltage generates certain phase difference between MODE_PLLIN and CLKOUT.
  • Output voltage range from 0.6V to 3.3V
  • Maximum continuous output current of 40ADC
  • Operating frequency of 350KHz
  • Efficiency of 87.7% at VIN = 12V, VOUT = 1V, IOUT = 40A
  • Load transient of 81mV at VIN = 12V, VOUT = 1V, ISTEP = 0A to 10A
