Analog Devices Inc. LTM4648/LTM4649 Buck DC/DC μModule Regulators
Analog Devices Inc. LTM4648/LTM4649 Step-Down DC/DC μModule Regulators' high-efficiency design delivers up to 10A continuous current. The LTM4648/LTM4649 has a wide output voltage range set by a single external resistor, requiring only bulk input and output capacitors. The current mode architecture and high switching frequency permit a fast transient response to line and load changes without sacrificing stability.
The Analog Devices LTM4648/LTM4649 feature frequency synchronization, programmable multiphase operation, output voltage tracking for supply rail sequencing, thermal shutdown, and overvoltage and overcurrent protection.
