   产品概述 返回TOPL1R嘉泰姆

The CXDC6579G series of regulators are integrated circuits that provide all active functions for a step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation. These devices are avail-able in fixed output voltages of 3.3V, 5V, 12V, and an adjust-able output version. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation†, and a fixed-frequency oscillator. The CXDC6579G series operates at a switching frequency of 150 kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Available in a standard 5-lead TO-220 package with 5 pins lead in one line options, and a 5-lead TO-263 surface mount package. A standard series of inductors are available from several different manufacturers optimized for use with the CXDC6579G series. This feature greatly simplifies the design of switch-mode power supplies. Other features include a guaranteed ±2% tolerance on output voltage under specified input voltage and output load conditions, and ±10% on the oscillator frequency. 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 tem perature shutdown for complete protection under fault conditions.
