It operates from a 3V to 16V supply rail and delivers a single positive output with a maximum duty cycle of 96.5%, allowing the output to approach the input voltage closely. Switching frequency reaches up to 300kHz, and the controller includes an Enable control feature for on/off sequencing. ## Through-hole 8-DIP package for prototyping and low-volume builds Housed in an 8-pin DIP (0.300\" row spacing, 7.62mm body width) with through-hole mounting, the MAX1649CPA+ is suited for breadboard prototyping, socketed evaluation, and low-volume production where hand-assembly or wave-solder is preferred. The 8-PDIP package (Supplier Device Package 8-PDIP) has a 0.100\" pin pitch and standard 0.300\" width, compatible with common DIP sockets and perfboard layouts. ## Active production, ROHS3 compliant It is ROHS3 compliant (2011/65/EU + 2015/863), with no lead, mercury, cadmium, or other restricted substances above threshold limits.","metaTitle":"MAX1649CPA+ Buck Controller, 3-16V, 300kHz, 8-DIP","metaDescription":"Analog Devices MAX1649CPA+ step-down buck controller, 3V-16V supply, up to 300kHz switching, 96.5% duty cycle, 8-DIP package.
