LTM4650AEV#PBF

LTM4650A is a dual 25A or single 50A output switching mode step-down DC/DC µModule® (micromodule) regulator with ±1% total DC output error over line, load and temperature. Included in the package are the switching controllers, power FETs, inductors and all supporting components. This LTM4650A supports two outputs with an output voltage range of 0.6V to 5.5V, each set by a single external resistor. Its high efficiency design delivers up to 25A continuous current for each output. Fast internal control loop compensation allows for fast transient response to minimize output capacitance when powering FPGAs, ASICs and processors. Typical applications are telecom and networking equipment, storage and ATCA cards, industrial equipment.

• Input voltage range from 4.5V to 16V
• Higher light load efficiency and wider VOUT range than LTM4650-1
• Differential remote sense amplifier
• Current mode control/fast transient response
• Multiphase parallel current sharing up to 300A
• Internal temperature monitor, Au pad/ball finish
• Adjustable switching frequency or synchronization, over current foldback protection
• Selectable burst mode® operation, pulse-skipping mode operation
• Soft-start/voltage tracking, -40°C to 125°C temperature range
