Description

The LMR14030SSQDDARQ1 is a DC-DC buck converter from Texas Instruments, designed for automotive applications. It belongs to the LMR14030-Q1 series, which is qualified for automotive use and compliant with AEC-Q100 standards. This device can efficiently convert a wide input voltage range (4 V to 40 V) to a lower, regulated output voltage, delivering up to 3 A of continuous current. The buck converter operates at a fixed frequency, providing a balance between performance and compactness, which is ideal for space-constrained applications.
Key features include high efficiency, low quiescent current, and built-in protection mechanisms such as thermal shutdown, cycle-by-cycle current limit, and an adjustable soft-start to prevent inrush current. The LMR14030SSQDDARQ1 is housed in a thermally-enhanced, 8-pin SO PowerPAD package, allowing for effective heat dissipation. This makes it suitable for use in automotive systems like infotainment, instrument clusters, and body electronics where reliability and performance are critical.

Equivalent

The LMR14030SSQDDARQ1 is a step-down voltage regulator from Texas Instruments.

Pinout

The LMR14030SSQDDARQ1 is a buck converter from Texas Instruments. It typically comes in a 8-pin WSON (Wettable Flank) package. Here is a brief description of its pin functions:
1. SW (Switch Output): Connects to the inductor. This pin carries the switching current of the regulator.
2. GND (Ground): Ground reference for the device. All control circuits are referenced to this pin.
3. FB (Feedback): Connects to the output of the power supply to set the output voltage via an external resistor divider.
4. EN (Enable): A high level on this pin enables the device; a low level disables it. Can be used for power sequencing.
5. VIN (Input Voltage): Supplies power to the device. This is the input voltage to be regulated.
6. BOOT (Bootstrap Capacitor): Provides a bootstrap capacitor connection for the high-side FET driver.
7. RT (Switching Frequency Setting Resistor): Connects to a resistor to set the switching frequency.
8. NC (No Connection): Typically not connected internally, often used for trace routing purposes.
This concise summary outlines the basic functionality of each pin in the device.
