1.22. IC7905 (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
