The SC2608B is a versatile voltage-mode PWM control-
ler designed for use in step down DC/DC power supply
applications. A simple, fixed frequency, highly efficient
buck regulator can be implemented using the SC2608B
with minimal external components. The input voltage
range is from +5V to +12V. Internal level shift and drive
circuitry eliminates the need for an expensive P-channel,
high-side MOSFET. The small device footprint allows for
compact circuit design.
SC2608B features include temperature compensated
voltage reference, triangle wave oscillator, current limit
comparator, and an externally compensated error ampli-
fier. Current limit is implemented by sensing the voltage
drop across the bottom MOSFET R
DS(ON)
.
The SC2608B operates at a fixed frequency of 250kHz
providing an optimum compromise between efficiency ,
external component size, and cost.
SC2608B has a thermal protection circuit, which is
activated if the junction temperature exceeds 150
O
C.
