Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LMR14020QDPRTQ1 device is a 40V, 2A buck regulator with integrated high-side metal oxide semiconductor field effect transistor (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 extended family offers 3.5A and 5A current options in pin-to-pin compatible packages, including the LMR14030-Q1 and LMR14050-Q1. The regulators have a quiescent current of 40µA in sleep mode, making them ideal for battery-powered systems. An ultra-low current of 1µA in shutdown mode further extends battery life. The regulators have a wide range of adjustable switching frequencies, which allows efficiency or external component size to be optimised. Internal loop compensation means that the user does not have to undertake the tedious task of designing loop compensation components. It also minimises the number of external components in the device. Precision enable inputs simplify regulator control and system power sequencing. In addition, the device has a variety of built-in protection features: cycle-by-cycle current limit protection, thermal sensing and thermal shutdown protection against excessive power consumption, and output overvoltage protection.

The LMR14020QDPRTQ1 is available in a 10-pin WSON package with an exposed pad for low thermal resistance.
