The UCC3808D-2G4 is a DC-to-DC synchronous switch controller IC that has been widely adopted by professional power management designers in the construction of both isolated and non-isolated DC-to-DC power supplies. It features a single-ended primary-side control method based on pulse-width modulation that supports a wide input voltage range of 4.5 V to 20 V and output voltages from 0.8 V to Vdd.

The UCC3808D-2G4 is designed to provide a high level of flexibility and performance in applications ranging from low noise efficiency-optimized point-of-load designs to high current FET-driven synchronous buck configurations. It contains an integrator for the constant on-time control loop, allowing the designer to select the optimal operating conditions for the synchronous switch control loop. This control logic can be adjusted to accurately control transient response and system efficiency resulting in a more reliable and robust power solution.

The UCC3808D-2G4 has a wide range of protection features including under-voltage lockout, output over-voltage protection, and input under-voltage protection. The device also has thermal shutdown and current limit protection to ensure that the system is reliable and robust. The output voltage can also be adjusted with the use of a resistor divider, allowing the designer to easily set the desired output voltage.

The UCC3808D-2G4 has broad application possibilities for DC-to-DC power supplies. It can be used in non-isolated point-of-load applications, as well as in isolated power supplies for telecom, industrial and computing applications. It\'s also well-suited for LED lighting and solar inverter applications.

The UCC3808D-2G4 features a synchronous switch controller IC that operates according to a constant on-time control loop, which functions by recirculating current at a duty cycle that is determined by the value of the output voltage inductor current. The control loop will increase the duty cycle of switch control pulse when the output voltage drops due to the output load current increase. Inversely, it will decrease its duty cycle when the output voltage increases. The switching frequency can be adjusted by connecting an external resistor and capacitor to the UCC3808D-2G4\'s PFD pin, allowing the designer to optimize the transient response and overall system efficiency.

In summary, the UCC3808D-2G4 is a versatile and highly reliable DC-to-DC synchronous switch controller IC designed for use in a wide range of power management applications. Its constant on-time control loop ensures excellent transient response and system efficiency, while its wide range of protection features make it suitable for use in various industrial and consumer applications.
