LTM4633EY#PBF

LTM4633 is a µModule® (micromodule) 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. This device’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. It is used in applications such as telecom, networking and industrial equipment, high density point of load regulation etc.

• Total DC output error is ±1.5% maximum
• Current mode control/fast transient response
• Frequency synchronization
• Output overvoltage and overcurrent protection
• Multiphase operation with current sharing on VOUT1 and VOUT2
• General purpose temperature monitors

• Input supply current each channel is 1.5A typ at (VOUT = 1.5V, IOUT = 10A)
• Operating junction temperature is -40°C to 125°C
• Package style is 144-lead BGA
