The SN51DP itself generates minimal heat, but the external power MOSFET can become quite hot during operation. Consider these thermal guidelines:
In standard television applications (such as boards using the TP.S506.PB801 main board architecture), the SN51DP functions as a boost topology controller. It steps up an incoming 12V supply to the higher DC voltages required to power series-connected LED backlight strings. For now, the closest match in actual guides:
When designing with the SN51DP, the datasheet (or this compilation) emphasizes these points:
The SN51DP has the following timing characteristics:
The SN51DP consists of a differential driver and a differential receiver. The driver section converts a single-ended input signal into a balanced differential signal, while the receiver section converts the balanced differential signal back into a single-ended output signal. Compensation Pin
: Commonly found in MSOP-10 or MSOP-8 surface-mount packages.
The SN51DP is available in an 8-pin SOIC package. The pin configuration is as follows:
: LED Current Setting. Controls the maximum output current fed into the backlight string.
