The MAX1685EEE+ from Analog Devices (formerly Maxim Integrated) 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.
This device features a wide input voltage range of 2.7V to 14V, providing design flexibility. The output voltage is preset to 3.3V but can be externally adjusted from 1.25V to VIN. With a switching frequency of 600kHz, it allows for the use of smaller external components. The regulator achieves high efficiencies of up to 96% due to its low on-resistance power switch and built-in synchronous rectifier.
Operational modes include fixed-frequency, normal, low-power, and shutdown, allowing for power conservation when full load is not required. The MAX1685EEE+ operates at 600kHz, enabling smaller external components. It also supports synchronization to an external clock. Other features include a 100% duty cycle for low-dropout applications, an auxiliary 3V/5mA output, and a ±1% accurate reference output.
The MAX1685EEE+ is available in a space-saving 16-QSOP package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C.
