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.

3.0V to 7.0V
