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.
