MAX1917EEE+T

Overview

The MAX1917EEE+T is a compact, high-efficiency dual-output switching regulator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It utilizes a boost topology to generate two independent output voltages of 3.3 V and 28 V from a single input source ranging from 700 mV to 5.5 V. The device delivers an output current of 350 mA with a fixed switching frequency of 300 kHz. Designed for surface-mount installation in a QSOP-16 package, it operates within a temperature range of -40°C to +85°C and features a load regulation of 0.5%.

Feature Summary

• Dual-output capability generating both low-voltage logic levels and higher voltage rails from a single input
• Boost topology enables operation from ultra-low input voltages starting at 700 mV
• Compact QSOP-16 packaging designed for space-constrained portable applications

Applications

• Portable electronic devices requiring multiple power rails
• Battery-powered systems needing efficient voltage boosting
• Embedded circuits utilizing dual-output power management
