FAC1501H

SEMICONDUCTOR TECHNICAL DATA FAC1501H 3A 150KHz PWM Buck DC/DC Converter General Description Features The FAC1501H 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 extenal 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 FAC1501H is available in TO-220B-5L TO220-5L and TO-263-5L packages. 5V and adjustable output versions Output adjustable from 1.23V to 54V Fixed 150KHz frequency internal oscillator Guaranteed 3A output load current Input voltage range up to 60V Low power standby mode, IQ typically 80 µA TTL shutdown capability Excellent line and load regulation Requires only 4 external components High efficiency Thermal shutdown and current limit protection Available in TO-220B/TO220 and TO-263 packages Applications Simple High-eff...
