LTC3676HLXE#PBF

Special Purpose Regulators Overview

The LTC3676HLXE#PBF is a power management integrated circuit designed for application processors, manufactured by Analog Devices Inc. It features seven buck converters housed in an LQFP-48 package. The device operates with an input voltage range of 2.7 V to 5.5 V and provides adjustable output voltages from 800 mV to 5.5 V. Each regulator supports up to 2.5 A of output current. The switching frequency ranges from 1.125 MHz to 2.25 MHz. It functions within a temperature range of -40°C to +150°C and draws 23 µA of quiescent current.

Special Purpose Regulators Feature Summary

• Integrates seven independent synchronous buck regulators into a single compact package.
• Designed specifically to provide comprehensive power rails for complex application processors.
• Supports high efficiency operation through wide switching frequency selection.

Special Purpose Regulators Applications

• Powering multi-rail application processor systems
• Embedded computing platforms requiring multiple regulated voltage domains
