The MAX1771ESA+T is a versatile DC-DC switching controller designed by Analog Devices Inc. It excels in step-up and step-up/step-down applications, offering high efficiency up to 90% over a wide load current range. The device accepts input voltages from 3V to 16.5V and operates at a switching frequency of up to 300kHz, enabling the use of small, surface-mount magnetics.
This controller utilizes a unique current-limited pulse-frequency-modulation (PFM) control scheme, providing the benefits of PWM converters with significantly lower supply current, typically 110µA maximum. It features an enable control function and drives an external N-channel MOSFET, allowing for output power up to 24W. The MAX1771ESA+T is housed in a compact 8-SOIC surface-mount package, suitable for space-constrained designs.
Key applications include positive LCD-bias generators, flash memory programmers, high-power RF power-amplifier supplies, and battery-powered portable devices. Its low supply current and high efficiency make it an ideal choice for power management in portable communicators, palmtops, and hand-held terminals.
