降压式 DC-DC
功能特点
产品名称:降压式 DC-DC
产品型号:HG2592
产品描述:
The HG25912 seriesofregulatorsaremonolithicintegrated
circuits that provide all the active functions for a step-down
(buck) 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, 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 HG2592 seriesoperatesataswitchingfrequencyof
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, 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 LM2596
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 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.
