MAX1700EEE

MAX1700EEE Description

The MAX1700EEE from Analog Devices Inc./Maxim Integrated is a high-efficiency, adjustable boost DC-DC switching regulator designed for applications requiring stable voltage conversion from low input voltages. This obsolete but robust IC delivers an output current of 1.1A (Switch) with an input voltage range of 0.7V to 5.5V, making it suitable for battery-powered and portable devices. The output voltage is adjustable from 2.2V to 5.5V, providing flexibility for various load requirements. Operating at a 300kHz switching frequency, it balances efficiency and component size, ideal for space-constrained designs. Packaged in a 16-QSOP tube, it features surface-mount compatibility and is REACH unaffected, ensuring compliance with environmental regulations.

MAX1700EEE Features

• Wide Input Range (0.7V–5.5V): Supports ultra-low-voltage sources like single-cell batteries.
• Adjustable Output (2.2V–5.5V): Configurable for diverse applications.
• High Switching Frequency (300kHz): Enables compact inductor and capacitor selection.
• 1.1A Switch Current: Delivers sufficient power for moderate loads.
• Non-Synchronous Topology: Simplifies design while maintaining efficiency.
