Shenzhen Meiyuxin Technology Co., Ltd. 【Sell Automotive Chips】LMR14050SQDDARQ1 SIMPLE SWITCHER® Automotive 40V, 5A 2.2MHz Step-Down Converter with 40uA IQ Quality Assurance New Original! ! !

Product Description:

The LMR14050SQDDARQ1 device is a 40-V, 5-A step-down regulator with integrated high-side MOSFET. With a wide input voltage range of 4V to 40V, the device is suitable for regulating unregulated power supplies in a variety of applications from industrial to automotive. The regulator draws 40µA of quiescent current in sleep mode, making it ideal for battery-powered systems. And it has an ultra-low current of 1μA in shutdown mode to further extend battery life. The regulator's wide adjustable switching frequency range allows optimization of efficiency or external component size. Internal loop compensation means that the user does not have to undertake the tedious work of designing loop compensation components. And also to minimize the external component count of the device. A precision enable input simplifies regulator control and system power sequencing. In addition, the device has several built-in protection features: cycle-by-cycle current limit protection, thermal sensing and thermal shutdown protection for excessive power dissipation, and output overvoltage protection.
