G5ELM2596
Simple Switcher Power converter 150kHz 3A Step-Down Voltage Regulator
Description
The G5ELM2596 series of regulators are monolithic integrated circuits that provide all active functions for a step-down (buck) switching
regulator, capable of driving 3A load with excellent line and load regulation. These devices are available in fixed output voltage of 3.3v, 5v,
12v 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 G5ELM2596 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 several different lead bend options.
A standard series if inductors are available from several different manufactures optimized for use with the G5ELM2596 series. This feature
greatly simplifies the design of switch-mode power supplies. Other feature include a guaranteed ±4% to tolerance on output voltage under
specified input voltages and output load conditions, and ±15% on the oscillator frequency. External shutdown is included, featuring 80uA
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.
