A5973D013TR

Импульсный понижающий DC-DC стабилизатор, регулируемый, 4В-36В (Vin), 1.235В-35В, 2А, HSOP-8.

The A5973D013TR is a step-down monolithic power Switching Regulator with a minimum switch current limit of 2.25A, so it is able to deliver up to 2A DC current to the load depending on the application conditions. The output voltage can be set from 1.235 to 35V. The device uses an internal P-channel DMOS transistor (with a typical RDS(on)of 250mR) as switching element to minimize the size of the external components. An internal oscillator fixes the switching frequency at 250kHz. Having a minimum input voltage of 4V 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.
