Synchronous Step Down Controller

SiP12201

Vishay Siliconix

DESCRIPTION

SiP12201 is a synchronous step down controller de-

signed for use in dc-dc converter circuits requiring out-

put currents as high as 10 amperes. SiP12201 is de-

signed to require a minimum number of external com-

ponents, simplifying design and layout. It accepts input

voltages from 4.2 V to 26.0 V, providing an adjustable

output with voltage ranging from 0.6 V to 20 V.

SiP12201 includes a combination Compensation/

Shutdown pin. Protection features include undervolt-

age lockout, output current limit, and thermal shut-

down.

SiP12201 is available in a lead (Pb)-free MLP33-10

package and is specified to operate over the range of

- 40 °C to 85 °C.
