DESCRIPTION  
The SP6122 is a PWM/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 micro 8 package.
