Texas Instruments LMR38020 | Demoboard LMR38020

Description

The LMR38020 synchronous buck converter is designed to regulate over a wide input voltage range, minimizing the need for external surge suppression components. The LMR38020 operates during input voltage dips as low as 4.2 V, at nearly 100% duty cycle if needed, making the device an excellent choice for wide input industrial applications and MHEV/EV systems.
