Sn51dp Datasheet Pdf Now
ON-Bright (often represented as ON-Brig in market listings). Package Type: SOP-10 or MSOP-10 (10-pin configuration). Function: LED Backlight Driver (Boost Topology).
: A 12V line fuels the VIN pin. The IC initiates an internal oscillator.
If an SN51DP is not readily available, it can be replaced with one of the following alternatives:
Finding an official, clean copy of the SN51DP Datasheet PDF can be challenging because it is primarily an OEM component. This article provides a comprehensive overview of its physical properties, internal architecture, pin configurations, step-by-step diagnostic procedures, and structural component bypass methods. 🛠️ Overview of Technical Specifications sn51dp datasheet pdf
SN510P, OB3350CP (SOP-8 equivalent with layout modification) SN51DP Pinout Configuration
: Keep the trace routing between the external MOSFET source terminal, the current-sensing resistor, and Pin 5 (CS) as brief as humanly possible. High-frequency switching noise on this path can cause erratic dimming behavior.
If you are sourcing this chip online, it is widely available through international distributors like UTSource Components or bulk hardware suppliers on AliExpress Wholesale . Always match the component suffixes and package footprint to ensure an exact fit on your PCB. ON-Bright (often represented as ON-Brig in market listings)
: Surface-mount SSOP-10 / MSOP-10 (Mini Small Outline Package, 10 pins).
Current sense input used to monitor inductor peak current for cycle-by-cycle protection.
In typical operations, the SN51DP drives a step-up (boost) converter circuit. When the TV turns on, a BL_ON or ENA signal triggers the IC, while the DIM pin controls brightness using duty cycles. Troubleshooting LED Backlight Protections : A 12V line fuels the VIN pin
: Although the SSOP-10 package is small, ensure the primary ground pin ( Pin 4 ) is tied directly to a substantial copper pour area on the printed circuit board to effectively siphon away heat during extended operations.
appears to be a specific electronic component, likely a voltage regulator or power management IC (PMIC) from a manufacturer such as Texas Instruments
