MAXIM INTEGRATED / ANALOG DEVICES MAX1627ESA Buck Power Controller
The MAX1627ESA+ is a high-efficiency, step-down (buck) DC-DC controller packaged in an 8-pin NSOIC. It can deliver load currents ranging from 1mA to 2A and supports adjustable output voltages from 1.3V to 16V. The device uses an external P-channel MOSFET and current-sense resistor to provide flexible design options and improve efficiency. Its current-limited, pulse-frequency modulation (PFM) control scheme ensures excellent efficiency across a wide load range, drawing approximately 90µA when idle. Ideal for battery-powered applications, it enables operation at 100% duty cycle for minimal dropout voltage, thereby extending battery life. Its high switching frequency of 300kHz and simple circuit topology reduce PCB area and component costs, making it suitable for compact, low-cost DC-DC converters and applications transitioning from 5V to 3.3V in energy-efficient systems. Key features include a supply voltage range of 3V to 16.5V, operating temperature from -40°C to 85°C, low quiescent (90µA) and shutdown (1µA) currents, and a soft-start function for reliable startup. The external P-channel MOSFET allows output power greater than 12.5W, suitable for power management in consumer electronics, portable devices, and other applications demanding efficient voltage regulation. Note that market demand has extended lead times; delivery may fluctuate, and the product is exempt from discounts.
