MAX618EEE+

MAX618EEE+ Description

The MAX618EEE+ from Analog Devices Inc./Maxim Integrated is a high-performance, adjustable DC switching voltage regulator designed for boost (step-up) topologies. This surface-mount IC delivers an output current of 1.4A (switch) with a wide input voltage range of 3V to 28V, making it highly versatile for various power supply designs. The output voltage is adjustable from 3V to 28V, providing flexibility for diverse applications. Operating at a switching frequency of 250kHz, it balances efficiency and component size, suitable for compact designs. The 16QSOP package ensures space efficiency, while its ROHS3 compliance and REACH unaffected status meet environmental standards.

MAX618EEE+ Features

• Adjustable Output (3V–28V): Enables precise voltage regulation for dynamic load requirements.
• Wide Input Range (3V–28V): Supports operation from low-voltage sources like batteries or unstable supplies.
• High Output Current (1.4A): Ideal for powering moderate-load applications without external switches.
• Boost Topology: Efficiently steps up voltage for systems requiring higher output than input.
• 250kHz Switching Frequency: Reduces inductor size while maintaining efficiency.
• Non-Synchronous Rectification: Simplifies design with external diode flexibility.
• Robust Packaging (16QSOP): Compact and suitable for space-constrained PCB layouts.
• Environmental Compliance: ROHS3 and REACH compliant, with MSL 1 (Unlimited) shelf life.

MAX618EEE+ Applications

The MAX618EEE+ excels in applications requiring efficient voltage step-up and stable power delivery, such as:

• Portable Electronics: Battery-powered devices (e.g., handheld instruments, medical devices) needing regulated higher voltages.
• Industrial Systems: Sensor interfaces, actuators, or control circuits with variable input sources.
• Automotive Electronics: Auxiliary power supplies for infotainment or lighting systems.
• LED Drivers: Constant-voltage boost converters for LED arrays.
• Embedded Systems: Low-power microcontrollers or wireless modules requiring stable 5V/12V rails from batteries.

Conclusion of MAX618EEE+

The MAX618EEE+ stands out as a reliable, high-efficiency boost regulator with broad input/output flexibility, making it a top choice for engineers designing compact, power-sensitive systems. Its adjustable output, robust current handling, and compliance with environmental standards ensure suitability for industrial, automotive, and portable applications. Compared to similar models, its wide voltage range and non-synchronous topology offer design simplicity and cost efficiency, particularly in space-constrained or battery-operated scenarios.
