The MAX1771ESA+ is a versatile DC DC switching controller from Analog Devices, capable of both step-up and step-up/step-down conversion. It features a wide input voltage range from 3V to 16.5V and operates at a high switching frequency of 300kHz, allowing for the use of miniature external components.
This controller provides a maximum duty cycle of 92% and is designed to drive an external N-channel MOSFET, enabling it to power loads up to 24W. Its unique current-limited pulse-frequency-modulation (PFM) control scheme offers high efficiency, up to 90%, over a load current range of 30mA to 2A, while maintaining a low supply current of only 110µA maximum.
The MAX1771ESA+ is available in an 8-SOIC package and is suitable for surface mount applications. It is designed for applications requiring efficient power conversion, such as positive LCD-bias generators, flash memory programmers, and battery-powered portable devices.
