These values are fixed and cannot be changed on the transmitter side. An up to date list of available and compatible A6 transmitter coils can be found here (Texas Instruments Literature Number SLUA649): Capacitor selection is critical to proper system operation. The total capacitance value of 147nF is required in the center coil of the resonant tank. This capacitance is not a standard value and therefore several must be combined in parallel. It is recommended to use 100nF + 47nF, as these are very commonly available. NOTE A total capacitance value of 147nF/100 V/C0G is required in the center coil and 133nF/100V/C0G in the side coils of the resonant tank to achieve the desired resonance frequency. The capacitors chosen must be rated for 100 V operation. Use quality C0G type dielectric capacitors from reputable vendors such as KEMET, MURATA or TDK. Dynamic Power Limiting™ With an optional 5-V to 12-V boost converter, a 5-V input can enable a 12-V WPC A6 transmitter. The Dynamic Power Limiting™ (DPL) feature allows operation from a 5-V supply with limited current capability (such as a USB port). When the 5-V input voltage is observed drooping, the output power is dynamically limited to reduce the load and provides margin relative to the supply’s capability. Anytime the DPL control loop is regulating the operating point of the transmitter, the LED will indicate that DPL is active. The LED color and flashing pattern are determined by the LED Table. If the receiver sends a Control Error Packet (CEP) with a negative value, (for example, to reduce power to the load), the transmitter in DPL mode will respond to this CEP via the normal WPC control loop. NOTE The power limit indication depends on the LED_MODE selected. Copyright © 2013, Texas Instruments Incorporated Submit Documentation Feedback 11 Product Folder Links: bq500412 |
