BP9916C datasheet

Description

BP9916C is a high precision Buck constant current LED driver. The device operates in critical
conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting.
The BP9916C integrates a 500V power MOSFET.

With patent pending MOSFET driving technique, the operating current of the IC is as low as 180uA. It doesn’t need the auxiliary winding for VCC supply. It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized.

PF7903BS datasheet led driver

Description

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.
