Analog Devices Inc. LTM4633/LTM4634 Buck DC/DC μModule Regulators

Analog Devices Inc. LTM4633/LTM4634 Triple Output Step-Down DC/DC μModule Regulators have three switching mode DC/DC converters in one space-saving, thermally enhanced 15mm × 15mm × 5.01mm BGA package. The current mode architecture and high switching frequency permit a fast transient response to line and load changes without sacrificing stability. Benefits and features for the LTM4633/LTM4634 from Analog Devices include soft-start, output voltage tracking, frequency synchronization, and multiphase parallel operation for supply rail sequencing. Additional features for fault protection include overcurrent protection, overvoltage protection, and temperature monitoring.
