Vishay Siliconix
DESCRIPTION
SiP12201 is a synchronous step down controller
designed for use in dc-dc converter circuits requiring
output currents as high as 10 amperes. SiP12201 is
designed to require a minimum number of external
components, 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 5 V.
SiP12201 includes an 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.
