DESCRIPTION
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 鈥渕icro鈥?/div>
parts, the
SP6122
has an array of value added features like optional hiccup mode, over
current protection, TTL enable, 鈥渏itter and frequency stabilization鈥?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.
