Introduction
The LMR38020 synchronous buck converter is used for regulation over a wide input voltage range, thereby minimizing the need for external surge suppression components. The LMR38020 can continue to operate at a duty cycle close to 100% as needed when the input voltage suddenly drops to 4.2V, making it an ideal choice for industrial applications with wide input voltage ranges and MHEV/EV systems. The LMR38020 uses a precision enable pin, providing flexibility by supporting direct connection to a wide input voltage or enabling precise control of device startup and shutdown. A power-good status flag with built-in filtering and delay functions provides a true indication of system status, eliminating the need for an external monitor. The device uses pseudo-random spread spectrum, has 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 improve efficiency at low operating frequencies or reduce the solution size at high operating frequencies. The device has built-in protection features, such as cycle-by-cycle current limiting, hiccup-mode short-circuit protection, and thermal shutdown in case of excessive power dissipation. The LMR38020 is available in an 8-pin HSOIC PowerPAD package.
