The EC1602 is a series of easy to use fixed and adjustable step-down(buck) switch-mode voltage regulators. These devices are available in fixed output voltage of 5V, and an adjustable output version. Both versions are capable of driving a 3A load with excellent line and load regulation.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed-frequency oscillator.
The output voltage is guaranteed to ±3% tolerance under specified input voltage and output load conditions. The oscillator frequency is guaranteed to ±15%. External shutdown is included, featuring typically 80 μA standby current. Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault conditions.
The EC1602 is available in TO-263-5L packages.
