DESCRIPTION

The SP6122 is a PWM/PFM minimum on-time controller designed to work from a single 3V-

5.5V 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 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.
