(Power stage) and the feedback control circuit is relatively accurate and greatly shortens the design cycle. The J2103A can be used in almost any power circuit that requires feedback control. Its feedback input (Vin) and reference voltage (Vref) use differential inputs without reference ground problems.

The configuration diagram of panel 1 for J2103A is shown in Figure 2. Figure 2 J2103A Panel Configuration I According to Figure 2, the J2103A provides two types of input/output ports: Banana jacks and Dupont connectors: a. You can select the Vcomp output using the Dupont terminals. By connecting pin 5 to pin 6 with a jumper capacitor, you can set Vcomp to open drain output.

Figure 3-3 USB Type-C Charging Port The USB Type-C charging port shown on Figure 3-3 is for charging only. When J2103A is being charged, the power switch will automatically turn off and cannot be operated. A 5V, 15W USB charger adapter...
There is an OSC to Vcomp port signal attenuation ratio of 20dB. The J2103A operates with a single power supply, and the Vcomp output range is 0~10V. Therefore, the strength of the OSC signal, represented by Vosc/10, must be lower than the DC bias value of Vcomp under no clamp condition.
+26dBm, and there is a 20dB attenuation from OSC to Vcomp. The bandwidth is greater than 1MHz. d. Four LTO batteries are connected in series to power the J2103A. They can be fully charged in about 30 minutes and can work continuously for more than 8 hours with Vcomp=10V at no-load and the OSC port not connected.
