3 Description
The LM2576 series of regulators are monolithic
integrated circuits that provide all the active functions
for a step-down (buck) switching regulator, capable
of driving 3-A load with excellent line and load
regulation. These devices are available in fixed output
voltages of 3.3 V, 5 V, 12 V, 15 V, and an adjustable
output version.
Requiring a minimum number of external
components, these regulators are simple to use
and include fault protection and a fixed-frequency
oscillator.
The LM2576 series offers a high-efficiency
replacement for popular three-terminal linear
regulators. It substantially reduces the size of the heat
sink, and in some cases no heat sink is required.
A standard series of inductors optimized for use
with the LM2576 are available from several different
manufacturers. This feature greatly simplifies the
design of switch-mode power supplies.
Other features include a ±4 tolerance on output
voltage within specified input voltages and output
load conditions, and ±10 on the oscillator frequency.
External shutdown is included, featuring 50-μA
(typical) standby current. The output switch includes
cycle-by-cycle current limiting, as well as thermal
shutdown for full protection under fault conditions.
The LM76003 requires very few external components
and has a pinout designed for simple, optimum PCB
layout for EMI and thermal performance. See the
device comparison table to compare specs.
LM2576属于集成电路(IC) > DC DC 开关稳压器。美国德州仪器公司制造生产的LM2576稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC(电源管理集成电路)产品族中的产品是元器件级设备,用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件,设备提供的电力会通过该元件。
