A5970D  
1.5A switch step down switching regulator  
for automotive applications  
Features  
Qualified following the AEC-Q100  
requirements (temperature Grade 3),  
see PPAP for more details.  
Temperature range -40 °C to 85 °C  
Up to 1 A DC output current  
SO-8  
Operating input voltage from 4.4 V to 36 V  
Output voltage adjustable from 1.235 V to 35 V  
Low dropout operation: 100 % duty cycle  
250 kHz Internally fixed frequency  
Voltage feedforward  
Description  
The A5970D is a step down monolithic power  
switching regulator capable to deliver up to 1 A at  
output voltages from 1.2 V to 35 V.  
The device uses an internal P-channel D-MOS  
transistor (with a typical Rdson of 250 m) as  
switching element to minimize the size of the  
external components.  
Zero load current operation  
Internal current limiting  
Inhibit for zero current consumption  
Synchronization  
An internal oscillator fixes the switching frequency  
at 250 kHz.  
Protection against feedback disconnection  
Thermal shutdown  
Having a minimum input voltage of 4.4 V only, it is  
particularly suitable for 5 V bus.  
Pulse by pulse current limit with the internal  
frequency modulation offers an effective constant  
current short circuit protection.  
Applications  
Dedicated to automotive applications
