PF7900S (SOP8), IC-POWER CONTROLLER (SO8), , IC

9V to 27V Input Current Mode Boost Controller

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.
