ETA Releases “Little Green Point PD20W” Full Protocol Scheme with the Size of a Coin
The release time of iPhone12 is coming. However, manufacturers don’t give chargers. It is believed that those who want to buy new mobile phones of Apple are probably considering what kind of chargers to buy. ETA recommends a compact charger for you, namely “Little Green Point PD20W” and brings you a set of solutions.
Little Green Point 20W scheme has a built-in ETA8056 IC. The actual size of PCB: 25mm*23mm*22mm. Its size is equivalent to that of a coin.
Behind the small size is the iteration previously based on AC-DC chip with power tubes with a switching frequency of 80K released by ETA family after ETA felt the market demand of fast charging. For 20W-27W market, ETA releases ETA8056 and ETA8058, which integrates two low impedance high voltage power tube IC.
It can be seen that ETA8056 is packed with SOP-7 patch. It supports QR+CCM mode, wide VCC: 7-37v. 80K switching frequency supports the design of transformer with a small size.
In addition, ETA8056 can realize constant power and power reduction, which can be set through the chip VD pin when the voltage is low and the current is high, so that the current will not be very high. It can reduce synchronous rectification pressure and improve efficiency. In addition, the chip has constant power and reduced power, which can realize the current limiting function of the protocol chip at the primary stage without secondary current Sense resistor. The protocol chip has a strong selectivity.
