LMR38020/LMR38020-Q1 Buck Converter

Texas Instruments LMR38020/LMR38020-Q1 SIMPLE SWITCHER® Buck Converter is designed to regulate over a wide input voltage range, minimizing the need for external surge suppression components. The LMR38020/LMR38020-Q1 operates during input voltage dips as low as 4.2V, at nearly 100% duty cycle if needed, making it an excellent choice for wide input industrial applications and MHEV/EV systems.
