LG FLATRON W2234S SNI W2234S BNI LCD MONITOR SMPS and INVERTER SCHEMATIC
Power Supply Regulator and Back-light Inverter Circuit Diagram - LG Flatron W2234S-SNI - W2234S-BNI.Axx*QP Monitor xx * means sales region and module type (AxxIQP: INL 5ms, AxxVQP: AUO 5ms) SMPS SCHEMATIC Power Part. This part consists of the one 3.3V, and one 1.8V regulators to convert power which is provided 5V in Power board. 16V is provided for inverter, 16V is provided for LCD panel and 5V for micom. Also, 5V is converted 3.3V and 1.8V by regulator. Converted power is provided for IC in the main board. The inverter converts from DC16V to AC 700Vrms and operates back-light lamps of module.

Protectors Circuit on SMPS power supply
The simplest example SMPS which still uses 3 transistors (C3807, A1015 and power transistors) classic problem that often occurs is: - Problem in the feedback circuit can cause the output voltage B + over so that it can endanger the aircraft as a whole. For example elco erupted, pcb burnt burnt by over-heated, horizontal transistor short. - Problem on feedback circuits may cause power regulator transistor is damaged due to over current transistor (eg, due to the 47k resistor transistor circuit on the secondary error detector value is delayed). - If the input ac voltage drops can cause the power regulator transistor is damaged, due to over current transistor If the secondary there is a power transistor short can cause damage over current regulator. - Protectors are designed to make the SMPS SMPS "reliable will not be damaged" if there are things that go wrong as mentioned above. SMPS Circuit SMPS circuit using IC systems generally are designed with a surge protector, which inc...
