A5970AD Up to 1 A step down switching regulator for automotive applications
The A5970AD is a step down monolithic power switching regulator with a switch current limit of 1.35 A so it is able to deliver more than 1 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 device uses an internal P-channel DMOS transistor (with a typical RDS(on) of 250 m Ω ) as switching element to avoid the use of bootstrap capacitor and guarantee high efficiency.
An internal oscillator fixes the switching frequency at 500 kHz to minimize the size of external components. Having a minimum input voltage of 4 V only, it is particularly suitable for 5 V bus, available in all computer-related applications.
Pulse by pulse current limit with the internal frequency modulation offers an effective constant current short circuit protection
