LTC3634IUFD#PBF

Special Purpose Regulators Overview

The LTC3634IUFD#PBF is a monolithic synchronous step-down DC/DC converter designed for DDR power applications. It integrates three buck regulators within a QFN-28 package. The device accepts an input voltage range of 3.6 V to 15 V and provides adjustable output voltages from 600 mV to 3 V. Each channel delivers up to 3 A of output current. Operating at a fixed switching frequency of 4 MHz, the regulator achieves low static current consumption of 15 uA. It supports operation across temperatures from -40°C to +125°C.

Special Purpose Regulators Feature Summary

• Integrates three independent high-efficiency synchronous buck converters in a single monolithic package
