The MAX1771CSA+T is a high-efficiency step-up DC-DC switching controller designed by Maxim Integrated. It achieves up to 90% efficiency over a load range of 30mA to 2A, making it suitable for battery-powered devices.
This controller features a unique current-limited pulse-frequency-modulation (PFM) control scheme, providing the benefits of PWM converters with significantly lower supply current (110µA max). It supports an input voltage range of 2V to 16.5V and can deliver up to 24W of output power. The output voltage is preset at 12V but can be adjusted using external resistors.
With a high switching frequency of up to 300kHz, the MAX1771CSA+T allows for the use of miniature surface-mount magnetics. It drives an external N-channel MOSFET switch. Applications include positive LCD-bias generators, flash memory programmers, and portable communication devices.
The device is available in a surface-mount package.
