com SiP12202 New Product Vishay Siliconix Synchronous Step Down Controller 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 adjustable output with voltage ranging from 0.
6 V to 5.
5 V.
SiP12202 includes a combination Compensation/ Shutdown pin.
Protection features include undervoltage 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.
