A7986A  
3 A step-down switching regulator for automotive applications  
Datasheet  
-
production data  
Applications  
Dedicated to automotive applications  
Automotive LED driving  
Description  
HSOP8 exposed pad  
The A7986A is a step-down switching regulator  
with a 3.7 A (min.) current limited embedded  
power MOSFET, so it is able to deliver up to 3 A  
current to the load depending on the application  
conditions.  
Features  
Qualified following AEC-Q100 requirements  
3 A DC output current  
The input voltage can range from 4.5 V to 38 V,  
while the output voltage can be set starting from  
0.6 V to VIN.  
4.5 V to 38 V input voltage  
Output voltage adjustable from 0.6 V  
250 kHz switching frequency, programmable  
Requiring a minimum set of external components,  
the device includes an internal 250 kHz switching  
frequency oscillator that can be externally  
adjusted up to 1 MHz.  
up to 1 MHz  
Internal soft-start and enable  
Low dropout operation: 100% duty cycle  
Voltage feed-forward  
The HSOP8 package with exposed pad allows  
the reduction of Rth(JA) down to 40 °C/W.  
Zero load current operation  
Overcurrent and thermal protection
