Description

If this Y-cap is connected to the primary GND, it should be connected to the negative terminal of the C1 (GND1) directly. Point discharge of the Y-cap also helps with ESD; however, the distance between these two points should be at least. 5mm according to safety requirements. Sense. Gate. Vdc. VDD. RI. FB. GND. SG6848 . Power Adapters/ Battery Chargers. The SG6848 and the SG6849 are excellent solutions for battery chargers used in devices such as cellular phones, cordless phones, PDAs, and digital cameras. They are also ideal for Flyback converters used by ink jet printers, video game consoles, HUBs, routers, portable audio players,. products and appliances that meet a one-watt standby standard. One-Watt standby power will be soon be required in all appliances. It is estimated that the total stand-by power costs USA US$ 3.5 billion per Year. System Generals Green -mode ICs: SG6848 . -.
