Internal soft-start

The SC202F is a high eﬃciency 500mA step-down regula-

tor that includes an integrated inductor inside the

package. The input voltage range makes it ideal for

battery operated applications with space limitations. The

SC202F operates at a ﬁxed 3.5MHz switching frequency in

normal PWM (Pulse-Width Modulation) mode. The

SC202F also includes fifteen programmable output

voltage settings that can be selected using the four

control pins, eliminating the need for external feedback

resistors. The output voltage can be fixed to a single

setting or dynamically switched between diﬀerent levels.

Pulling all four control pins low disables the output.

Over-voltage protection

The SC202F provides several protection features to safe-

guard the device under stressed conditions. These

include short circuit protection, over-temperature protec-

tion, under-voltage lockout, and soft-start to control

in-rush current. These features, coupled with the small

2.5 x 3.0 x 1.0 (mm) package, make the SC202F a versatile

device ideal for step-down regulation in products needing

high eﬃciency and a small PCB footprint.
