TPP36308 Temperature Rise Test


TPP36308 features a high-power density and compact TSOT23-6 package (2.90 mm × 1.60 mm) and can replace products in SOP-8 and TO-220 packages in low-power applications. This allows customers to save on-board space, aligning with the trend towards smaller product designs. Under test conditions with a 25°C ambient temperature, 12-V/24-V input, and 5-V@1.5-A output, the chip case temperatures were 43°C and 48.7°C, respectively.
