LMR604303SBRAKRQ1 TI DC-DC Converter | 9-WQFN-HR(2.5x2) | 3A, 36V

Product Overview

The LMR604303SBRAKRQ1 is a high-performance step-down DC-DC converter from Texas Instruments, designed for automotive and industrial applications. It operates over a wide input voltage range of 3.5V to 36V and delivers up to 3A of continuous output current. Housed in a compact 9-pin WQFN-HR package (2.5mm x 2.0mm), this device integrates high-side and low-side MOSFETs, enabling high efficiency and small solution size. The LMR604303SBRAKRQ1 features peak current-mode control, which provides fast transient response and easy loop compensation. With a switching frequency of 2.2MHz, it allows the use of small inductors and capacitors, further reducing board space. The device includes a full suite of protection features such as overcurrent protection (OCP), overtemperature protection (OTP), and undervoltage lockout (UVLO). It is AEC-Q100 qualified for automotive applications.
