SiP12202
Vishay Siliconix
DESCRIPTION
SiP12202 is a synchronous step down controller
designed for use in dc-dc converter circuits requiring
output currents as high as 10 amperes. SiP12202 is
designed to require a minimum number of external
components, simplifying design and layout. It accepts
input voltages from 2.7 V to 5.5 V, providing an adjust-
able output with voltage ranging from 0.6 V to 5.5 V.
SiP12202 includes a combination Compensation/
Shutdown pin. Protection features include undervolt-
age lockout, Power Good output, output current limit,
and thermal shutdown.
SiP12202 is available in a lead (Pb)-free MLP-33-10
package and is specified to operate over the range of
- 40 °C to 85 °C.
