Additional Infomation About Product

A5970AD Up to 1 A step down-switching regulator for automotive applications Datasheet - production data Application Dedicated to automotive applications Description SO-8 The A5970AD is a step-down monolithic power switching regulator with a minimum switch current Features limit of 1.35 A so it is able to deliver up to 1 A DC current to the load depending on the application Qualified following the AEC-Q100 conditions. The output voltage can be set from requirements (see PPAP for more details) 1.235 V to V . IN 1 A DC output current The device uses an internal P-channel DMOS Operating input voltage from 4 V to 36 V transistor (with a typical R of 250 m ) as DS(on) 3.3 V / ( 2%) reference voltage switching element to minimize the size of the external components. Output voltage adjustable from 1.235 V to V IN An internal oscillator fixes the switching frequency Low dropout operation: 100% duty cycle at 500 kHz. Having a minimum input voltage of 500 kHz Internally fixed frequency 4 V only it fits the automotive applications Voltage feed-forward requiring the device operation even in cold crank conditions. Pulse by pulse current limit with the Zero load current operation internal frequency modulation offers an effective Internal current limiting constant current short-circuit protection.
