The MAX1627ESA+T is a step-down (buck) DC-DC controller designed for high-efficiency power regulation. It operates from an input voltage range of 2.6V to 16.5V, making it suitable for a variety of battery-powered and green PC applications.
This controller utilizes a unique current-limited, pulse-frequency-modulation (PFM) control scheme that allows for up to 100% duty cycle, resulting in very low dropout voltage. It features a switching frequency of 300kHz, which helps reduce the size of external components like inductors. The device can deliver load currents from 1mA to over 2A and achieves over 90% efficiency from 3mA to 2A loads.
The MAX1627ESA+T is available in an 8-pin SOIC package and operates over an ambient temperature range of -40°C to +85°C. It requires external P-channel MOSFETs, offering flexibility for output power requirements exceeding 12.5W. Its low quiescent current of 90µA under light loads and 1µA shutdown current contribute to reduced system power consumption.
Key features include selectable 3.3V/5V or adjustable 1.3V to 16V output voltage options (depending on the specific model, MAX1626 vs MAX1627), soft-start to limit startup current, and a current-limited control scheme for reliable operation.
