150KHz 3A Step-Down Voltage Regulator
Product Description
Features
GS5256
150KHz 3A Step-Down Voltage Regulator
Product Description
The GS5256 series regulators are monolithic integrated circuits that provide all the active functions for a step-down switching regulator; capable of driving a 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V and an adjustable 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 GS5256 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 and a 5-lead TO-263 surface mount package.
A standard series of inductors are optimized for use with the GS5256 series. This feature greatly simplifies the design of switch-mode power supplies.
Other features include a guaranteed ±4% tolerance on output voltage under specified input voltage and output load conditions, and ±15% on the oscillator frequency. External shutdown is included, featuring typically 80μA 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.
