Lmr14030-q1 device is a 40V, 3.5A step-down regulator with integrated high side metal oxide semiconductor field effect transistor (MOSFET). The wide input voltage range of this device is 4V to 40V, which is suitable for regulating non regulated power supply in various applications from industry to automobile. Its extended series of products can provide 2 A and 5A current options in pin to pin compatible packages, including lmr14020-q1 and lmr14050-q1.
The static current of the regulator in sleep mode is 40 µ a, which is very suitable for battery powered systems. And it has 1 in off mode μ The ultra-low current of a can further prolong the service life of the battery.
The adjustable switching frequency range of the regulator is wide, which enables the efficiency or external component size to be optimized. Internal loop compensation means that users do not have to undertake the tedious work of designing loop compensation components. And it can also minimize the number of external components of the device. Precise enable input simplifies regulator control and system power sequencing. In addition, the device also has a variety of built-in protection functions: cycle by cycle current limiting protection, thermal sensing and thermal shutdown protection against excessive power consumption, and output overvoltage protection.
Lmr14030-q1 is packaged in 8-pin hsoic or 10 pin WSON with exposed pads for low thermal resistance.
