LM2576
3A Step-Down Voltage Regulator
GENERAL DESCRIPTION
The LM2576 Series are step-down switching
regulators with all required active functions. It is
capable of driving 3A load with excellent line and
load regulations. These devices are available in
fixed output voltages of 3.3V, 5V, 12V and an
adjustable output version.
The LM2576 series offers a high-efficiency
replacement for popular three-terminal linear
regulators. Also it requires a minimum number of
external components. It substantially not only
reduces the area of board size but also the size of
heat sink, and in some cases no heat sink is
required. The ±4% tolerance on output voltage
within specified input voltages and output load
conditions is guaranteed. Also, the oscillator
frequency accuracy is within ±10%. External
shutdown is included. Featuring 80µA (typical)
standby current. The output switch includes
cycle-by-cycle current limiting, as well as thermal
shutdown for full protection under fault conditions.
This series are offered in 5-pin TO-263,
TO-220 package.

AN-1149 Layout Guidelines for Switching Power Supplies (Rev. C)

PDF, 82 Кб, Версия: C, Файл опубликован: 23 апр 2013When designing a high frequency switching regulated power supply layout is very important. Using agood layout can solve many problems associated with these types of supplies. The problems due to a badlayout are often seen at high current levels and are usually more obvious at large input to output voltagedifferentials. Some of the main problems are loss of regulation at high output current
