Analog Devices DC2838A 电源管理开发电路板和套件
LT8365 DC to DC Converter and Switching Regulator Chip 245V to 255V Output Demonstration Circuit
An external compensation pin allows optimization of loop bandwidth over a wide range of input and output voltages and programmable switching frequencies between 100kHz and 500kHz. A SYNC/MODE pin allows synchronization to an external clock. It can also be used to select between burst or pulse-skipping modes of operation with or without spread spectrum frequency modulation for low EMI. For increased efficiency, a BIAS pin can accept a second input to supply the INTVCC regulator. Additional features include frequency foldback and programmable soft-start to control inductor current during startup.
The LT8365 is available in a thermally enhanced 16-lead MSOP package with four pins removed for high voltage pin spacings.
