Sn51dp Datasheet Pdf

The is a high-performance LED Backlight Driver Controller typically used in LED TV and monitor backlight systems. It is often found in the power supply or backlight inverter boards of major brands like Samsung and LG.

Based on reference schematics for LED TV driver applications: VIN (Input Voltage) DIM (Dimming Control) GATE (Gate Drive Output) GND (Ground) CS (Current Sense) ISET (Current Setting) FB (Feedback) COMP (Compensation) OVP (Over Voltage Protection) REF (Reference Voltage) Applications & Usage LED TV Repair: Commonly found on mainboards such as the TP.S506.PB801 used in TV brands like Arielli, Crown, and Felix. Protection Bypassing:

When a television mainboard featuring the SN51DP architecture fails (such as the widespread TP.S506.PB801 chassis), the issue often manifests as the .

By respecting the datasheet’s limits and applying the principles above, you will harness the full potential of the SN51DP in your next embedded or industrial project. sn51dp datasheet pdf

The SN51DP features a optimized to provide high-precision pulse width modulation (PWM) control and active safety feedback mechanisms. The internal routing maps out across the 10 pins as follows:

What is the TV or monitor you are servicing?

If the backlight flashes briefly and then goes out, check the voltage at Pin 9 (OVP). If it exceeds the threshold, the IC is shutting down to protect the circuit from an open LED string. The is a high-performance LED Backlight Driver Controller

Limits current through the external MOSFET via the CS (Current Sense) pin.

Current Sense input. Measures switching current through the primary external power MOSFET. GND System Ground reference point. 10 GATE The internal routing maps out across the 10

The SN51DP fundamentally runs a step-up (boost) converter loop. It receives an un-boosted DC supply (like a standard 12V board rail) on Pin 1. When the main board shifts into active mode, it pumps high-speed square-wave signals out of the .

The in liquid crystal display (LCD) applications. Commonly manufactured by ON-Brig and engineered in a compact 10-pin package (SSOP-10 or MSOP-10), this specialized controller regulates current delivery to LED strips within modern television panels. It is widely found on standard Chinese mainboards (such as the TP.S506.PB801) used by consumer TV brands like Arielli, Crown, and Felix.
