UCC3808ADTR-2 is a high-precision DC/DC switching controller from Texas Instruments with adjustable, programmable output voltage and housekeeping functions. It is a circuit-level integrated, full-function, constant frequency, peak- current-mode, DC/DC doubler/tripler controller. This integrated voltage regulator uses advanced BiCMOS technology for maximum performance, high current and low power consumption, and is available in the low-profile DTR and DSSOP packages.This integrated controller provides an excellent compromise between performance, power consumption, and cost-effectiveness, making it suitable for a wide range of applications. It is available in a wide range of voltages and current capacities, making it suitable for a variety of applications ranging from cell phones to automotive electronics and high-end server boards.The UCC3808ADTR-2 operates in several modes of operation, like basic current mode, peak current mode, independent voltage feedback, and voltage follower modes. The switching frequency is adjustable through an external capacitor, enabling the design to be easily optimized for requirements. The adjustable built-in reference allows fine tuning of the output voltage level to within ±1%. Additionally, the built-in power-on/off sequence ensures safe power-on of the output, and it comes with programmable features for various applications.The UCC3808ADTR-2 operates with a constant switching frequency of up to 400 kHz to reduce noise and make for more efficient design. It also features an overvoltage protection circuit that ensures that the load does not get overloaded due to a high output voltage, and an overcurrent protection circuit that protects from unstable loads. The UCC3808ADTR-2 also provides other features such as an Auto-Frequency Detect circuitry, to ensure a stable and noise-free performance if the switching frequency is below a certain predetermined value, as well as a skip cycle mode which allows the system to operate in its most efficient mode when the output power is very low.To increase efficiency, the UCC3808ADTR-2 comes with built-in power-saving features like a short-on detect circuit for minimum output current, and a spread-spectrum frequency modulation for lower EMI emissions . Additionally, the built-in enable/disable control (EN/DIS) function allows the circuit to operate either in active mode or standby mode with very low power consumption.The UCC3808ADTR-2 is a highly complete DC/DC switching controller and a very precise voltage regulator designed to meet the needs of a wide range of applications. It offers precise voltage regulation, high reliability, excellent efficiency, low cost, and a low profile package. Its adjustable, programmable output voltage make it ideal for a variety of applications, and its on-chip power optimization features make it suitable for a wide array of power control needs.
