The A5973D is a step-down monolithic power switching regulator with a minimum switch current limit of 2.25 A so it is able to deliver up to 2 A DC current to the load depending on the application conditions. The output voltage can be set from 1.235 V to 35 V. The high current level is also achieved thanks to an HSOP8 package with exposed frame, that allows to reduce the Rth(JA)down to approximately 40 °C/W. The device uses an internal P-channel DMOS transistor (with a typical RDS(on)of 250 mΩ) as switching element to minimize the size of the external components. An internal oscillator fixes the switching frequency at 250 kHz. Having a minimum input voltage of 4 V only it fits the automotive applications requiring the device operation even in cold crank conditions. A pulse-by-pulse current limit with the internal frequency modulation offers an effective constant current short-circuit protection. https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2020-06-16 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2021-04-03 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2021-04-15 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2021-07-16 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2021-12-04 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2022-04-07 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2022-06-13 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2022-06-25 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2022-07-03 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2024-03-11 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2024-07-30 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2024-11-20 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2025-01-23 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2025-03-01 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2025-07-04 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2025-08-01 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2025-09-16 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2025-11-27 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2026-01-22 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2026-01-31 https://elecena.pl/product/16972814/a5973d013tr-up-to-2-a-step-down-switching-regulator-for-automotive-applications 2026-05-24
