DESCRIPTION  
The SP6122 is a PFM minimum on-time controller designed to work from a single 5V or  
3.3V input supply. It is engineered specifically for size and minimum components count,  
simplifying the transition from a linear regulator to a switcher solution. However, unlike  
other “micro” parts, the SP6122 has an array of value added features like optional hiccup  
mode, over current protection, TTL enable, “jitter and frequency stabilization” and a fault  
flag pull down pin. Combined with reference and driver specifications usually found on  
more expensive integrated circuits, the SP6122 delivers great performance and value in  
a 8 pin MSOP package.
