LT3837EFE#PBF Working Principle

The LT3837EFE#PBF utilizes a proprietary current-mode control architecture for fast transient response, excellent line and load regulation, and output accuracy. The voltage detector and high voltage gate driver integrated on the device enable the use of an external transistor to drive the output switch. When the output voltage drops or rises below the programmed setpoint and the input voltage is above the UVLO, the voltage detector triggers the high voltage gate driver to drive the output switch on. The device automatically times the output switch turn-on and turn-off based on the programmed peak current limit and the sense resistor current threshold. If the output voltage is outside the programmed voltage window, the voltage detector will trigger the high voltage gate driver to force the output switch off. The controller operates over a wide range of output voltages, currents, and power levels and provides accurate output regulation.

The LT3837EFE#PBF is a highly efficient, fast-responding switching regulator controller with a high voltage MOSFET switch integrated. It is designed specifically for low power, high efficiency applications requiring either isolated or non-isolated DC/DC conversion. The device’s voltage detector, high voltage gate driver, and integrated MOSFET switch together offer superior performance and reliability, making it an ideal choice for a wide variety of applications.
