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 micro 8 package. TYPICAL APPLICATION CIRCUIT
