Quality Control: Learn More
The Analog Devices Inc./Maxim Integrated MAX1639ESE is a highly efficient, 1MHz buck (step-down) DC-DC controller IC. Designed for positive output voltage regulation, this transistor driver offers a single output phase and a maximum duty cycle of 90%. Its frequency control feature allows for adjustable switching frequencies between 300kHz and 1MHz, providing flexibility in power supply design. The controller operates from a 4.5V to 5.5V supply voltage and features synchronous rectification for improved efficiency. Packaged in a 16-SOIC (0.154", 3.90mm width) surface mount configuration, this component is suitable for applications in the telecommunications and computing industries. It operates within an ambient temperature range of -40°C to 85°C.
