Monitors the current flowing through the external switching MOSFET via a low-value resistor. ISET / REF Current Setting
Standalone digital pulse width modulator (DPWM) and LED driver. Operating Voltage: Minimum supply voltage of to a maximum of Temperature Range: Operating temperature from -20°C to +85°C (some sources list up to 130°C). Package Type: 10-pin SSOP/MSOP (Small Outline Package). Resolution: Programmable resolution up to Pin Configuration (Typical 10-Pin Layout)
The is a switching power IC designed for high-efficiency DC-DC conversion in a compact package. It is most commonly known as an LED backlight driver found in LCD television sets. This chip is widely used in popular TV models from various brands, including the Konka LED42E330N and the Amoi 32-inch LCD TV series.
Please check the top marking on the chip again. If it is an 8-pin chip, it could also be an SN65 or SN75 series transceiver. If you can provide the number of pins or the manufacturer logo, I can help locate the exact document. sn51dp datasheet pdf
to verify if the IC itself is still operational, though this is only recommended for diagnostic purposes.
If an SN51DP is not readily available, it can be replaced with one of the following alternatives:
