MAX8667ETEHR+

Overview

The MAX8667ETEHR+ is a quad-output power management IC (PMIC) from Analog Devices Inc./Maxim Integrated, designed for compact electronic systems. It integrates two synchronous buck regulators and two low-dropout (LDO) linear regulators within a single package. The device operates with an input voltage range of 2.8V to 5.5V and supports output voltages adjustable from 600mV to 3.3V. It features a fixed switching frequency of 1.5MHz and delivers up to 1.2A of output current. The component is housed in a 16-pin TQFN-EP package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates two synchronous buck converters and two LDO linear regulators for comprehensive power regulation
• Supports high-frequency operation at 1.5MHz to minimize external passive component size
• Provides flexible output voltage adjustment ranging from 600mV to 3.3V
• Designed for space-constrained applications through compact surface-mount packaging

Applications

• Power supply regulation in portable medical devices
• Voltage management in compact consumer electronics
