                                                SP6128ASEY-L Overview
Capsuled in the 14-TSSOP (0.173, 4.40mm Width) package, the switching controller can be used for a wide range of applications. dc motor controller is suitable for 1  output generation. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. 3V~5.5V is the operating voltage and supply voltage of the dc control. A -40°C~85°C TA dc switcher is not a problem. It can switch at 300kHz. The Surface Mount makes it ideal for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Current Limit. This part's supplier dc dc controller package would be 14-TSSOP.
