The LTM4633 μModule® (power module) regulator combines three complete 10A switching mode DC/DC converters into one small package. Included in the package are the switching controllers, power FETs, inductors, and most support components. The LTM4633’s three regulators operate from 4.7V to 16V input rail(s) or 2.375V to 16V with an external 5V bias. The VOUT1 and VOUT2 output range is 0.8V to 1.8V, while the VOUT3 output range is 0.8V to 5.5V. Each output is set by one external resistor.

High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The device supports frequency synchronization, multiphase parallel operation of VOUT1 and VOUT2, soft-start and output voltage tracking for supply rail sequencing.

Fault protection features include overvoltage protection, overcurrent protection and temperature monitoring. The power module is offered in a space saving, thermally enhanced 15mm × 15mm × 5.01mm BGA package. The LTM4633 is RoHS compliant with Pb-free finish.

Applications

  • Telecom, Networking and Industrial Equipment

LTM4633 Demo Board | High Efficiency, Triple Output Step-Down μModule Regulator

LTM4633 Demo Board | High Efficiency, Triple Output Step-Down μModule Regulator

Product Detail

Demonstration circuit 1905B features the LTM4633EY, a high efficiency, triple output step-down power μModule® regulator. The input voltage range is from 4.7V to 16V with a common input source, or 2.375V to 16V with an external bias supply. The output voltage range is 0.8V to 1.8V for channels 1 and 2, and 0.8V to 5.5V for channel 3. Derating is necessary for certain VIN, VOUT, frequency, and thermal conditions. See Table 1 in the user guide for Thermally Viable Operating Conditions. The DC1905B offers access to the TRACK/SS pins, allowing the user to program output tracking or soft-start period. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE jumper (JP4) selects pulse-skipping mode for noise sensitive applications or Burst Mode® operation in less noise sensitive applications. Channels 1 and 2 can be connected in parallel for a single 20A output solution with optional jumper resistors. The LTM4633 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit 1905B.
