PF7900 9V to 27V Input Current Mode Boost Controller Specification Rev. 1.4 Features  Wide Input Range: 9V to 27V  Adjustable Switching Frequency Setting  Current Mode Control  300mV Current Sensing Reference  Over Current Protection  Over Temperature Protection  Output Over Voltage Protection  Input Over Voltage Protection  PWM Dimming Input Applications  Front-End Stage of LED Backlight  LED Lighting GENERAL Description The PF7900 is a wide-input voltage boost controller which can be operated from 9V to 27V. The special dimming input helps to synchronize this device with multi-channel current matching ICs or MOSFETs for LED applications such as LED backlight or LED lighting. PF7900 integrated the current mode PWM controller with a high driving capability MOSFET driver, over current protection, and input/output over voltage protection in a SOP-8 package to minimize the PCB size as well as the component counts. The adjustable frequency setting helps users to select the optimized operation frequency.
