UCC3810DWTRG4

 Introduction of UCC3810DWTRG4

The UCC3810DWTRG4 is a Switched Mode Power Supply (SMPS) control IC that belongs to the UCC3810 series, which offers high efficiency, low power consumption, and flexible programmability for a wide range of applications. It is manufactured by TI and operates directly from the rectified universal mains. It supports valley or zero voltage switching for minimum switching losses, efficient quasi-resonant operation at high power levels, frequency reduction at low power standby, and cycle skipping mode at very low loads. It also provides various protection features, such as safe restart mode, continuous mode protection, overvoltage protection, short winding protection, undervoltage protection, overtemperature protection, and overcurrent protection. It has a high level of integration, giving a very low external component count.
