U6335 switching power supply chip is a high-performance primary control power switch

The U6335 switching power supply chip is a high-performance primary-control power switch that provides high-precision constant voltage and constant current performance, especially suitable for small power off-line charger applications and LED Christmas lights. The U6335 switching power supply chip has a VDD low pressure self-powered module that supports a PSR architecture of two windings. It also has a fast start function, allowing VDD to use a large capacity (22uf or 30uf) electrolytic capacitance, so that the power supply can accommodate low temperature applications such as LED Christmas lights. Main features of the U6335 switching power supply chip: With VDD low-voltage self-power supply, transformers can remove auxiliary windings Fast start function Line BOP function when starting Integrated 800V high voltage power BJT ± 5% constant current, constant voltage accuracy Multi-mode primary side control method Workless Adjustable line loss compensation Constant current compensation for integrated line voltage and load voltage Integrated and perfect protection features: Short circuit protection (SLP) Over temperature protection (OTP) Circular limit flow protection (OCP) FB overvoltage protection (FB OVP) Wired voltage undervoltage protection during startup (LINE BOP) VDD overvoltage protection Package form SOP-7 The U6335 switching power supply chip also has a line voltage undervoltage protection function at startup, which avoids an abnormal operating state when the PSR is too low. The U6335 switching power supply chip is typically applied to 12W (85 - 265VAC) charger. U6335 switching power supply chip integration has a variety of protection: VDD undervoltage protection (UVLO), VDD overvoltage protection (VDD OVP), intercepting flow protection (OCP), short circuit protection (SLP) and VDD clamp, FB overvoltage Protection (FB OVP), starting time line voltage undervoltage protection (LINE BOP).
