The MAX772ESA+ is a step-up switching controller designed by Analog Devices (formerly Maxim Integrated) for high-efficiency DC-DC conversion. It provides up to 90% efficiency across a load range of 10mA to 1A, making it suitable for battery-powered applications.
This controller utilizes a unique current-limited pulse-frequency-modulation (PFM) control scheme, offering the benefits of PWM converters with significantly lower supply current (110µA max). Its high switching frequency of 300kHz allows for the use of small, surface-mount magnetics.
The MAX772ESA+ accepts input voltages from 2V to 16.5V and can drive external N-channel MOSFET switches to power loads up to 15W. The output voltage can be preset or adjusted using two resistors. It is housed in an 8-SOIC package and supports surface mount.
Key applications include palmtops, handy terminals, positive LCD-bias generators, portable communicators, and flash memory programmers.
