General 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 component 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

Key Features

  • such as 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 an 8 pin MSOP package.
