We are using Wireless charging IC BQ51003. Our device is designed for 500mA and the ILIM is 330 ohms. Without connecting load,the voltage at Vrect is 6.5 - 7 V and Vout is 5v. When connecting the load of 10 ohms at Vout of wireless charging IC there is a voltage drop at Vrect and Vout,the measured voltage at Vrect is 3.6V and Vout is 3.3 - 3.5 V. This same occurs when we change our device for 350 mA and ILIM for 560 ohms. But when we change our device for 250mA and ILIM for 845 ohms,there is no voltage drop at Vrect and Vout during the load condition.what will be the reason for the voltage drop when designed for 550 mA and 330 mA. We need our device to be work at 550 mA.
