Lm2576hvt-adj to-220-5 switch regulator original genuine
explain
Lm2576 series regulator is a monolithic integrated circuit that provides all effective functions for step-down switching regulator. It can drive 3A load and has excellent line and load regulation performance. These devices can provide 3.3V, 5V, 12V, 15V fixed output voltage and adjustable output version. This kind of regulator not only needs few external components, but also is simple and easy to use. It also has fault protection and fixed frequency oscillator.
Lm2576 series can provide an efficient alternative to common three terminal linear regulators. It significantly reduces the size of the radiator and eliminates the need for a radiator in some cases. Several different manufacturers can provide a standard series of inductors, which can be optimized for use with lm2576. This feature greatly simplifies the design of switching mode power supply.
Other characteristics include that the device has an output voltage tolerance of ± 4% and an oscillator frequency tolerance of ± 10% under rated input voltage and output load conditions. With external shutdown function, the standby current (typical value) is 50 μ A。 The output switch has cycle by cycle current limit and thermal shutdown function to provide comprehensive protection under fault conditions.
The new product lmr33630 provides lower BOM cost, higher efficiency, smaller solution size (reduced by 85%) and many other features. Lm76003 requires few external components. The pin distribution design can simplify the PCB layout and provide better EMI and thermal performance.
