The under the terms of compliance with modern world standards for household switching power supplies, the  BN44-00498A  module  provides  for the use of a power factor correction unit (Power Factor Correction).  The PFC circuit is an up-and-down flyback converter based on The  SPC7011F  Controller  .  of The reactance of Electrolytic Capacitor The filter of AT A MAINS The Frequency of 50-60 Hz IS Not More usually Within last 20-30 ohm and ITS CHARGE Directly from The Open Network through Diodes Could REACH of TENS IF NO Amperes per Pulse Filtering is used.
As a result of the PFC conversion operation, an increased voltage on the capacitor (about 380V) can not directly open the led diodes, at the anode of which the voltage will always be somewhat less (about 300V) and then its charging current will always BE Limited by The the PWM Controller Elements.  of As A Result, The Envelope of High-Frequency impulses of The Current being Consumed Will REPEAT The Shape and Phase of The INPUT Sinusoidal Voltage.  of The Presence of Increased Voltage (+ 380V) ON The Network Capacitor indicates The serviceability of the PFC node.

The main featur The BN44-00498A module specifies the use of a power factor correction unit (power factor correction) according to the terms of the world standard for modern household switching power supplies.The PFC circuit is an up/down flyback converter based on the SPC7011F controller.Electrolytic capacitors for mains filters typically have a reactance of not more than 20-30 ohms at a frequency of 50-60 Hertz. If a filter is not used, the charge directly charged from the network through open-circuit diodes can reach Tens of amps per pulse.Es of the SAMSUNG UE40EH5300W:

The matrix (LED panel) LTJ-400HM08-L is installed.   
In the matrix control, the Timing Controller (T-CON) BN41-01797A is used.   
To power the backlight LEDs, a converter is used, combined with the power supply, Controlled by the PWM SLC2012M The IS Controller.   
of The Necessary for Power Supplies All the TV sets are Formed by the SAMSUNG UE40EH5300W The Power Module1 BN44-00498A or the using ITS Analogs The SQD2011K (STR3A161HD Standby), SPC7011F (the PFC), FSFR1700XS Chips.   
MainBoard - Mainboard ( Motherboard) is a module BN41-01812A, using CPU chips: SEMS27;   NAND FLASH KLM2G1HE3F-B001;   EEPROM: 24C256;   SDRAM K4B2G1646C-HCK0 and others.
Tuner BN40-00232A provides reception of television programs and tuning to Channels.
