MAX1771CPA Description

Short technical summary and product information.

The MAX1771CPA is a versatile step-up and step-up/step-down DC-DC switching controller manufactured by Analog Devices (formerly Maxim Integrated). It is designed to provide up to 90% efficiency across a load range of 30mA to 2A, making it suitable for battery-powered applications.

 

This controller features a unique current-limited pulse-frequency-modulation (PFM) control scheme, offering the benefits of PWM converters with significantly lower supply current (110µA max). It supports input voltages from 3V to 16.5V and operates at a high switching frequency of up to 300kHz, allowing for the use of miniature surface-mount magnetics.

 

The MAX1771CPA drives an external N-channel MOSFET switch and can power loads up to 24W. The output voltage is preset at 12V but can be adjusted using external resistors. Its control features include an enable function, and it is housed in an 8-pin DIP package suitable for through-hole mounting.

 

Key electrical specifications include a 3V to 16.5V input range, a 12V preset or adjustable output, and a maximum switching frequency of 300kHz. The device operates within a temperature range of 0°C to 70°C.
