SC2618
Miniature PWM Controller
for Buck Regulator
Features
Applications
Graphics IC Power supplies
Embedded, low cost, high efficiency converters
Revision: September 19, 2005
Typical Application Circuit
The SC2618 is a hysteretic mode PWM controller de-
signed for high efficiency, low cost “Point of Load” appli-
cations.
The hysteretic control scheme allows the use of ceramic
output capacitors without the need for compensation
components and difficult calculations.
An internal soft start prevents output voltage from start
up overshoot. A “Hiccup” short circuit protection provides
protection against output short circuits as well as ad-
verse input supply sequencing.
Operating Frequency up to 500kHz
Input supply from 5V to 12V
0.5A gate drive capability
Internal soft start
Internal, trimmed bandgap reference (
±1%)
