UCC3808AN-1G4

The UCC3808AN-1G4 is a high-efficiency switched-mode power supply (SMPS) controller chip that is well suited for regulating DC-DC and AC-DC converters. It integrates features such as high efficiency, low output voltage ripple, protection, and low current consumption. This chip is ideal for a variety of high-power applications, from DSP processors to industrial motors and lighting systems.The UCC3808AN-1G4 core operates using a linear signal modulation technique, enabling it to achieve both low output voltage ripple and high efficiency across a wide range of voltage inputs. It also performs fast transient response to sudden changes in the load. The controller has an adjustable output voltage range of 0.9V to 105V and its switching frequency can be programmed up to 600kHz.This chip supports multiple output voltage schemes such as constant voltage (CV), constant current (CC), constant power (CP), active power-factor correction (PFC), energy-saving, and active-clamp reset (ACR) modes. It can also be configured to provide synchronous as well as asynchronous operation.The UCC3808AN-1G4 uses unique protection features such as current limit, shutdown and input under-voltage lockout. It has built-in over-temperature protection and thermal shutdown. Its built-in short-circuit protection ensures the output voltage will not exceed the reference value even under extreme conditions. The device also supports line-age transients and common-mode transient immunity for uninterrupted operation.The UCC3808AN-1G4 features a programmable architecture, allowing it to be tailored to specific application requirements. It also has extended temperature range of -40C to +125C, making it suitable for high temperature environments.Overall, the UCC3808AN-1G4 is an excellent choice for DC-DC and AC-DC power conversion applications. Its high efficiency, high current limiting, low output voltage ripple, protection, and low current consumption make it ideal for a wide range of high-power applications.
