A8498  
Wide Input Voltage 3.0 A Step Down Regulator  
Features and Benefits  
Description  
8 to 50 V input range  
Integrated DMOS switch  
Adjustable fixed off-time  
Highly efficient  
The A8498 is a step down regulator that will handle a wide  
input operating voltage range.  
The A8498 is supplied in a low-profile 8-lead SOIC with  
exposed pad (package LJ). Applications include:  
Applications with 8 to 50 V input voltage range needing  
buck regulator for 3.0 A output current  
Adjustable 0.8 to 24 V output  
Consumer equipment power  
Uninterruptible power supplies (lead acid battery  
charger)  
Automotive telematics: 9 to 16 V input, with higher  
voltage protection  
12 V lighter-powered applications (portable DVD, etc.)  
Point of Sale (POS) applications  
Industrial applications with 24 or 36 V bus
