* 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.
* The following instruments shall be used for measuring ripple noise.
1. Probe having impedance ratio of 1:1.
2. Oscilloscope having frequency characteristic of 100MHz or more.

MTBF
50,000 hour
(Mean Time Between Failure) Cooling Condition Natural Air Shock 98
Shock test consists of pivoting the power supply, from one edge of it’s bottom side, on a flat surface
(such as wood having thickness of 10mm or more) and allowing the opposite edge to fall from a height of 50mm to this surface.
The test is performed three times on each edge of the bottom side of the power supply

Dielectric Strength Voltage
AC-DC 1.5K VAC 3 SEC 10 mA. Between Primary and All Secondary Circuits.
Safety
Insulation Resistance
Insulation resistance shall be more than 8M ohm (at DC 500V) Between Primary Live, Neutral line and Secondary.
* Above tests are performed at room temperature in non-condensing atmospheric
conditions
