The LMR38010FSQDDARQ1 synchronous buck converter is designed to regulate over a wide input voltage range, minimizing the need for external surge suppression components. The LMR38010-Q1 is ideal for 48V battery automotive applications and MHEV/EV systems due to its ability to continue operation at near 100% duty cycle as needed when the input voltage drops to 4.2V.

The LMR38010FSQDDARQ1 uses precision enable terminals to provide flexibility by enabling direct connection to a wide input voltage or precise control of device startup and shutdown. Power good flags with built-in filtering and delay provide a true indication of system status, eliminating the need for an external monitor. The device uses pseudo-random spread spectrum for ultra-low EMI, and the switching frequency can be configured between 200kHz and 2.2MHz to avoid noise-sensitive frequency bands. Additionally, the frequency can be selected to increase efficiency at low operating frequencies or reduce solution size at high operating frequencies.
