Additional Infomation About Product

A5970D Up to 1 A step-down switching regulator for automotive applications Datasheet - production data Protection against feedback disconnection Thermal shutdown Applications SO-8 Dedicated to automotive applications Description Features The A5970D is a step-down monolithic power Qualified following the AEC-Q100 switching regulator with a minimum switch current requirements (see PPAP for more details) limit of 1.35 A so it is able to deliver up to 1 A DC 1 A DC output current current to the load depending on the application conditions. The output voltage can be set from Operating input voltage from 4 V to 36 V 1.235 V to V . IN 3.3 V / ( 2%) reference voltage The device uses an internal p-channel DMOS Output voltage adjustable from 1.235 V to V IN transistor (with a typical R of 250 m ) as DS(on) Low dropout operation: 100% duty cycle switching element to minimize the size of the external components. 250 kHz Internally fixed frequency Voltage feed-forward An internal oscillator fixes the switching frequency at 250 kHz. Having a minimum input voltage of Zero load current operation 4 V only it fits the automotive applications Internal current limiting requiring the device operation even in cold crank Inhibit for zero current consumption conditions. Pulse by pulse current limit with the internal frequency modulation offers an effective Synchronization constant current short-circuit protection. Figure 1.
