com SiP12201 New Product Vishay Siliconix Synchronous Step Down Controller 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 undervoltage lockout, output current limit, and thermal shutdown.
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.
