The MAX640ESA+T from Analog Devices is a high-efficiency, low quiescent current step-down DC-DC converter. It operates with an input voltage range of 4V to 11.5V and provides an output current of up to 225mA. The device features a current-limiting PFM control scheme, offering the benefits of PWM converters with significantly lower supply current.
The output voltage can be preset to 3.3V or adjusted by the user to any voltage between 1.3V and the input voltage. This makes it suitable for applications requiring flexible voltage regulation. The MAX640ESA+T includes an internal 1A power MOSFET switch, simplifying designs by minimizing component count.
This regulator is ideal for replacing linear regulators in applications where high efficiency is critical, such as portable instruments and handy-terminals. Its low quiescent current of 10µA ensures extended battery life in power-sensitive devices. The device is available in an 8-SOIC package, suitable for surface mount applications.
Key electrical characteristics include an input voltage range of 4V to 11.5V and a maximum output current of 225mA. The output voltage is adjustable from 1.3V up to the input voltage, with a preset option for 3.3V. The operating temperature range is -40°C to 85°C.
