Compensation, Control and Monitoring
nn Input Voltage Range: 30V to 58V
nn Output Voltage Range: 0.5V to 1.5V
nn ±3% Output Current Readback Accuracy (–20° to 125°C)
nn 88% Efficiency for 48V to 1V at 50A
nn ±0.5% Output Voltage Accuracy Over Temperature
nn 400kHz PMBus-Compliant I2C Serial Interface
nn 16mm × 16mm × 7.72mm BGA Package The LTM®4664 is a complete non-isolated 48V input high
efficiency step-down µModule® regulator with dual 25A
outputs. The switching controllers, power MOSFETs, inductors
and supporting components are included. Only external
capacitors are needed to complete the design. Operating over
a 30V to 58V input voltage range, the LTM4664 supports an
output voltage of 0.5V to 1.5V at up to 75W. An intermediate
output at 25% • VIN is also available. The LTM4664 product
video is available on the website. nn The LTM4664 dual 25A regulators utilize digitally programmable analog control loops, precision data acquisition circuitry and EEPROM with ECC. The LTM4664’s 2-wire serial
interface allows the 25A outputs to be margined, tuned …
