SP6122 Datasheet | Sipex

DESCRIPTION The SP6122 is a PWM/PFM minimum on-time controller designed to work from a single 3V5.5V input supply. It is engineered specifically for size and minimum ponent 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 such as optional hiccup mode, over current protection, TTL enable, “jitter and frequency stabilization” and a fault flag pull-down pin. bined with reference and driver specifications usually found on more expensive integrated circuits, the SP6122 delivers great performance and value in an 8 pin MSOP package.
