The MAX1771CSA+T is a versatile step-up and step-up/step-down DC-DC switching controller designed for high-efficiency power conversion. It operates with an input voltage range of 2V to 16.5V and can deliver up to 24W of output power.
This controller utilizes a unique current-limited pulse-frequency-modulation (PFM) control scheme, achieving up to 90% efficiency over a wide load range from 30mA to 2A. It features a low supply current of 110µA maximum and a shutdown current of 5µA maximum, making it ideal for battery-powered devices.
The MAX1771CSA+T supports a preset 12V output voltage or an adjustable output via external resistors. Its high switching frequency of up to 300kHz allows for the use of miniature surface-mount magnetics. The device drives an external N-channel MOSFET switch.
Packaged in an 8-SOIC surface-mount package, the MAX1771CSA+T is suitable for applications such as positive LCD-bias generators, flash memory programmers, and portable communicators.
