The LT1738EG#PBF is an isolated DC-DC converter power management integrated circuit (PMIC) specifically designed and optimized for low noise, high efficiency, and low cost. It provides multiple protection and control features, such as over current, over temperature, and under voltage protection, that results in reducing circuit complexity, eliminating external components and simplify system design. The comprehensive output voltage range and enable function makes it ideal for a wide range of AC/DC and DC/DC applications.

The LT1738EG#PBF is a non-isolated, buck mode DC/DC converter with a pulse-width-modulated (PWM) control topology. This topology enables the converter to deliver power from a wide input voltage range with excellent load and line transient conditions. The control loop offers dynamic, fast and efficient response to load and line transients, while maintaining excellent transient performance. The switching frequency is user selectable to match the desired output ripple, stability and transient performance for the application. The conversion efficiency is excellent, up to 90%, depending on the load.

The LT1738EG#PBF is highly integrated, requiring few external components and offering multiple protection and control features. Protections include over current, over temperature, and UVLO protections. This makes the LT1738EG#PBF an ideal solution for low cost, high efficiency and high performance applications, such as LED lighting and power supplies.

The LT1738EG#PBF offers excellent stability and robustness with a current mode control loop, fast transient response, excellent line and load regulation, and low electromagnetic interference (EMI). Additionally, the device provides multiple current sensing methods and the user can select the method that best suits the requirements of the application. The control loop feature frequency dithering to reduce EMI (electromagnetic interference) by spreading the energy around the EMI filter bandwidth.

The LT1738EG#PBF is a highly integrated, low cost, low noise and high efficiency PMIC that provides a complete power solution for AC/DC and DC/DC applications. It is an ideal solution for any application requiring an efficient, cost effective and reliable power solution.
