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.
