3 Description
The LMR51420 is a wide-VIN, easy-to-use SIMPLE
SWITCHER® synchronous buck converter capable of
driving up to 2-A load current. With a wide input range
of 4.5 V to 36 V, the device is suitable for a wide
range of industrial applications for power conditioning
from an unregulated source.
The LMR51420 operates at 500-kHz and 1.1-MHz
switching frequency to support use of relatively small
inductors for an optimized solution size. The device
has a PFM version to realize high efficiency at
light load and FPWM version to achieve constant
frequency, and small output voltage ripple over the full
load range. Soft-start and compensation circuits are
implemented internally, which allows the device to be
used with minimum external components.
The device has built-in protection features, such as
cycle-by-cycle current limit, hiccup mode short-circuit
protection, and thermal shutdown in case of excessive
power dissipation. The LMR51420 is available in a
6-pin SOT-23 package.
LMR51420YFDDCR属于集成电路(IC) > 稳压器 - DC-DC 开关稳压器。美国德州仪器公司制造生产的LMR51420YFDDCR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。
