MAX1685EEE Description

Short technical summary and product information.

The MAX1685EEE from Analog Devices is a high-efficiency, internal-switch, pulse-width modulation (PWM) step-down switching regulator. It is designed to power devices such as cellular phones, PDAs, and handy-terminals, delivering a guaranteed 1A output current. The device operates with an input voltage range of 2.7V to 14V, providing design flexibility.

 

The output voltage can be preset to 3.3V or externally adjusted from 1.25V to VIN. With a low on-resistance power switch and built-in synchronous rectifier, it achieves efficiencies of up to 96%. The MAX1685 operates at 600kHz, allowing for the use of smaller external components. It supports multiple modes of operation including fixed-frequency, normal, low-power, and shutdown modes to conserve power when needed.

 

Key features include a 100% duty cycle for low-dropout applications, an auxiliary 3V/5mA output, and a ±1% accurate reference. The device is available in a space-saving 16-QSOP package, suitable for surface mount applications. This regulator is ideal for applications requiring efficient power conversion in a compact form factor.
