LG 47LM5800-
LG 47LS5700 - LG 47LM6200 LED LCD TV Power Supply Regulator (SMPS) Circuit Diagram
Used
semiconductors: HS01G – STR A6059H – L6599AD - STF13NM60N (FET)
Firmware Version 1.00a. Checksum 0x2214
On
Condition:
In a moment of Power ON Signal activated, the current of 3.5V output
should be limited within 40mA (Max) at LCD TV condition for stability. Do not turn “Power ON” Signal on at the load
condition of 3.5V output, more than 40mA.
Total
regulation for each output circuit includes the results of input voltage
variation, load variation, warm-up drift and temperature change.
Ripple
and noise are measured at the end of output cable which are added a 0.1uF
ceramic capacitor and 47uF electrolytic capacitor. (Connected parallel).

Short
circuit protection between different output terminals is not considered.
Trip
point for over voltage indicates the operating point when the output voltage
slowly increases.
The
conditions of Over Current measurement Multi output (3.5V, 12V, 24V) is nominal
load state except an over current measurement.
