LMR14030SQDPRTQ1

The LMR14030SQDPRTQ1 is a high performance, low-noise, synchronous, step-down DC/DC converter with integrated FETs for 3A applications. Featuring an input voltage range of 4.5V to 36V, it provides up to 3A of output current with a highly efficient design. It provides a wide output voltage range from 0.588V to 28V which makes it suitable for a wide range of applications in automotive, industrial and communication systems. The LMR14030SQDPRTQ1\'s internal synchronous switching FETs enable high efficiency and low noise levels with a single external compensation capacitor.

The LMR14030SQDPRTQ1 is ideal for applications that require low output ripple and a wide input range, such as automotive systems power controllers, 3G/4G radios and other communications equipment, as well as automotive and industrial ethernet devices. It features a selectable current limit and short circuit protection and can be synchronised to an external clock or running off an internal clock. The device also features an enable control pin, an electric restart pin and an output voltage adjust pin.

The operating principle of the LMR14030SQDPRTQ1 is based on pulse width modulation (PWM) control. In PWM control the output voltage is balanced by varying the duty cycle of the switching pulses that are generated. These pulses are created by regulating the average current to the switching FETs which in turn is adjustable through the internal pulse width modulation (PWM) circuit. The output voltage is then compared with the voltage reference at an internal error amplifier and the difference is amplified and used to adjust the PWM current limit. This closed loop feedback process is used to maintain a precise output voltage.

The LMR14030SQDPRTQ1 DC/DC converter is designed for a wide range of applications and provides both high efficiency and low noise levels. The device\'s integrated FETs, precise output voltage trimming, over-current protection and selectable current limit and short circuit protection make it suitable for a variety of applications. Its wide input range and wide output voltage range make it ideal for automotive, industrial and communication systems.
