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.
150 KHz fixed frequency internal oscillator
Guaranteed 3A output load current
Input voltage range up to 40V
3.3V, 5V and adjustable output versions
Adjustable version output voltage range, 1.2V
to 37V
These regulators require a minimum number of external
components and are simpler to use by an internal frequency
compensation and a fixed – frequency oscillator.
±4% max over line and load conditions
Requires only 4 external components
Excellent line and load regulation specifications
Available in TO-220 and TO-263 packages
TTL shutdown capability
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
Low power standby mode, IQ typically 80 µA
High efficiency
The AMC2596 series feature a guaranteed ±4%
tolerance of output voltage over input to output load
conditions.
Thermal shutdown and current limit protection
