The bq51020 device integrates an ultra-low-impedance synchronous rectifier, a very-highefficiency post regulator, digital control, and accurate voltage and current loops. The bq51020 devices provide the AC/DC power conversion while integrating the digital control required. The IC complies with the WPC v1.1 communication protocol. Together with the bq500xxx primary-side controller transmitter, the bq51020 enables a complete contactless power transfer system for a wireless power supply solution. By utilizing near-field inductive power transfer, the secondary coil embedded in the mobile device can pick up the power transmitted by the primary coil. The voltage from the secondary coil is then rectified and regulated to be used as a power supply for down-system electronics. Global feedback is established from the secondary to the primary in order to control the power transfer process. A WPC system communication is digital -– packets are transferred from the secondary to the primary. Differential bi-phase encoding is used for the packets. The bit rate is 2Kbps. Various types of communication packets have been defined. These include identification and authentication packets, error packets, control packets, power usage packets and efficiency packets, among others. 2 Considerations with this EVM The bq51020EVM-520 evaluation module (PWR520-002) demonstrates the receiver portion of the wireless power system. This receiver EVM is a complete receiver-side solution that produces 5-W output power at up to 1-A load with adjustable output voltage. • The receiver can be used in any number of low-power battery portable devices as a power supply for a battery charger. With contact-free charging capability, no connections to the device are needed. • Highly-integrated wireless power receiver solution – Ultra-efficient synchronous rectifier – Very-high efficiency post regulator – WPC v1.1-compliant communication and control – Only one IC required between RX coil and DC output • Programmable output voltage to optimize performance for application • Adaptive Communication current limit (CM_ ILIM) for robust communication. • Supports 20-V max input • Low-power dissipative overvoltage clamp • Overvoltage, overcurrent, overtemperature protection • Low-profile, external pick-up coil • Frame is configured to provide correct receiver to transmitter spacing 2 bq51020EVM (5-W WPC) Integrated Wireless Receiver Power Supply Copyright © 2014, Texas Instruments Incorporated SLUUB03 – April 2014 Submit Documentation Feedback Modifications www.ti.com • • • • • • • • 3 Room above coil for testing with battery, key for Foreign Object Detection (FOD) tuning Options to adjust the input current limit and output voltage using resistors Flexibility for Foreign Object Detection (FOD) tuning Adjustable resistor that can be used to set RFOD Temperature sensing can be adjusted using external resistors Micro-USB connector for adapter testing configuration WPG LED indicator (turns on as VOUT goes high) PD_DET LED indicator --turns on as the RX is on TX pad Modifications See the data sheet (SLUSBX1) when changing components.

Otherwise, this causes a voltage drop and thermal issue. • Keep the trace resistance as low as possible on AC1, AC2, OUT, and PGND. • Use the appropriate current rating traces (width) the AC, OUT and PGND. • The PCB should have a ground plane (return) connected directly to the return of all components through vias (At least two vias per capacitor for power-stage capacitors, one via per capacitor for small-signal components). • The dissipation of heat path is important. Adding internal layers increases the thermal performance. Multiple vias in the PGND pins of the IC is recommended to decrease the thermal resistance in the board and allow much easier thermal dissipation through inner layer and power ground layers. • The via interconnect is important and must be optimized near the power pad of the IC and the GND. • 2-oz copper, or greater, is recommended • For high-current applications, the balls for the power paths should be connected to as much copper in the board as possible. This allows better thermal performance because the board conducts heat away from the IC. • It is always good practice to place high frequency bypass capacitors next to RECT and OUT. 8.3 Printed-Circuit Board Layout Example The primary concerns when laying a custom receiver PCB are as follows: • AC1 and AC2, GND return trace resistance • OUT trace resistance • GND connection • Copper weight ≥ 2 oz For a 1-A fast charge current application, the current rating for each net is as follows: • AC1 = AC2 = 1.2 A • BOOT1 = BOOT2 = 1 A • RECT = 50 mA • OUT = 1 A • COMM1 = COMM2 = 300 mA • CLAMP1 = CLAMP2 = 500 mA SLUUB03 – April 2014 Submit Documentation Feedback bq51020EVM (5-W WPC) Integrated Wireless Receiver Power Supply Copyright © 2014, Texas Instruments Incorporated 15 Layout and Bill of Material • • • www.ti.com ILIM = 10 mA AD = AD_EN = TS/CTRL = EN1 = EN2 = TERM = FOD = 1 mA PWR = 10 mA TI also recommends having the following capacitance on RECT and OUT: • RECT ≥ 10 μF • OUT ≥ 1 μF It is always good practice to place high-frequency bypass capacitors next to RECT and OUT of 0.1 μF.
