MAXIM INTEGRATED / ANALOG DEVICES MAX8640ZELT12T step-down DC-DC converter
The MAX8640ZELT12T is a compact, high-efficiency synchronous step-down DC-DC converter capable of delivering up to 500mA. Operating at switching frequencies of 4MHz and 2MHz, it is housed in a 6-pin μDFN package, making it suitable for applications where space-saving, efficiency, and low output ripple are critical. Featuring an internal PWM control scheme, it adjusts switching frequency to optimize efficiency and minimize output ripple across load conditions. The device supports factory preset output voltages from 0.8V to 2.5V, eliminating the need for external feedback components. Internal synchronous rectification enhances efficiency and replaces external Schottky diodes, while an internal fast soft-start reduces inrush current. The supply voltage range is from 2.7V to 5.5V, with operate temperatures from -40°C to 85°C, and an initial accuracy of ±1%. This converter is ideal for powering microprocessor and DSP cores, I/O power, industrial, and portable devices. Additional features include low output ripple, ultrasonic skip mode down to 1mA load, fast transient response, and thermal shutdown at +160°C.
