Package : SOP 8 Pin Type

Manufacturer: Powerforest


PF7903BS datasheet led driver


As the direct-type WLED backlight (DLED) becomes the trend for low cost TV, the PF7903BS driver IC is targeted for such applications. PF7903B is a wide input voltage range, single channel, boost WLED controller which can be operated from 9V to 27V. By using PF7903B, the low total BOM cost WLED driver can be achieved easily. PF7903B integrated the current mode PWM controller with a boost
MOSFET driver, over current protection, over temperature protection, over output voltage protection,
and input over voltage protection in a SOP-8 package to minimize the PCB size as well as the component counts.
