产品概述
描述
The A5975AD is a step-down monolithic power switching regulator with a minimum switch current limit of 3.1 A, it is therefore able to deliver up to 2.5 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 a HSOP8 package with exposed frame, that allows to reduce the RTHJ-A 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 500 kHz. Having a minimum input voltage ofonly 4 V, it fits automotive applications requiring device operation even in cold crank conditions. Pulse-by-pulse current limit with the internal frequency modulation offers an effective constant current short-circuit protection.-
