DESCRIPTION FEATURES
The AMC2596 series are highly integrated step down
voltage regulator capable of driving a 3A load with extremely
regulated output voltages over line & load regulation. These
devices are available in fixed output voltages of 3.3V. 5V and
an adjustable output versions.
These regulators require a minimum number of external
components and are simpler to use by an internal frequency
compensation and a fixed – frequency oscillator.
By operating a switching frequency of 150KHz, the
AMC2596 series require smaller sized filter components. This
feature makes the application design more cost effective than
lower frequency switch regulators. A standard 5-lead TO-220
package with several different lead bend options, and a 5-lead
TO-263 surface mount package is available
The AMC2596 series feature a guaranteed ±4% tolerance
of output voltage over input to output load conditions.
