GENERAL DESCRIPTION
The CBM2596 series of 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, 12V and an adjustable output
version.
Requiring a minimum number of external
components, these regulators are Simple to
use.
The CBM2596 series operates at a
switching frequency of 150kHz. Available in
standard 5-lead TO-220 package.
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
100μA standby current. Self protection
features include a two stage frequency
reducing current limit for output switch and
an over temperature shutdown for complete
protection under fault conditions. The over
temperature shutdown level is about 145℃
with 5℃ hysteresis.
