Video buffer.
1.19. IC2002 (RH-iXB986WJQZQ)
The monitor microprocessor is intended to communicate with the main microprocessor and to operate the system. It also controls power of the entire
system.
1.20. IC7801 (9NK2510067610) L6562DTR
Transition-mode PFC (Power Factor Corrector) controller.
The PFC circuit is adopted to improve the power factor of electricity and total harmonic distortion (THD).
Realised in BCD (Bipolar-CMOS-DMOS) technology.
Transition-mode control of Pre-Regulators.
Proprietary multiplier design for minimum THD (Total Harmonic Distortion) of AC input current.
Very precise adjustable output Over-voltage protection.
1.21. IC7904 (9NK2510293234) TNY264PN
Enhanced, Energy Efficient, Low Power Off-line Switcher.
It supplies a power supply voltage of BU5V.
Fully integrated auto restart for short circuit and open loop fault protection saves external component costs
Built-in circuitry practically eliminates audible noise with ordinary varnished transformer
Programmable line under voltage detect feature prevents power on/off glitches saves external components
Frequency jittering dramatically reduces EMI (~10 dB)- minimizes EMI filter component costs
