Description  
The SC20A is a low-cost, 20-Amp, non-isolated DC-DC converter with  
an amazingly small footprint of only 0.8 in2. Designed for today's high  
power microprocessors, the SC20A accepts either 5 V or 3.3 V inputs and  
offers outputs from 1.3 V to 3.3 V. The SC20A also uses an industry-  
standard pin-out making it easy to increase power in existing designs.  
Using Bourns Switch Power's proprietary V2TM architecture, the SC20A  
provides ultrafast transient response, improved line and load regulation, and  
very high efficiency. It also incorporates short-circuit protection, Enable / Disable  
control, output voltage trim, and remote sense.
