Power supply regulator board Circuit Diagram_LG 42" LED TV [LGP4247L-12LPB]
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.
Stand By Power Consumption
Output Voltage 3.5V - (STBY)
12V - 24V
POWER ON Vcc Circuit
ON/OFF High : Vcc ON _ Low : Vcc OFF
PROTECTIONS
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.
