FP6346 - Fiti

FP6346 3A PWM Buck DC/DC Converter

The FP63 46 seri es of regulators are monolithic integrated circuit s ca pable of driving 3 A load with excellent line and load regulation. These devices are available in fi xed output volt ages of 3. 3V, 5V, 12V, and an adjustable output version. These reg ulators requi re a minimum number of external com ponents a nd are sim pler to use by internal f reque.

Features

include a guara nteed ±4% tolerance on output voltage under specified input voltage and output load condition s, an d ±15% on the oscillator frequency. S elf prote ction feature s in clude current limit for the output swit ch and an ove r temperature shutdown fo r complete prote ction unde r fau lt conditions. The packages are available in a standard 5-lead TO-220, and 5-lead TO-263. Features
