Due to the communication packet that occurs at an approximate 250-ms rate, averaging of input current and voltage is required for good accuracy. Note that Dynamic Efficiency Scaling will improve efficiency at lower loads for lower total output currents. This is demonstrated with the higher value for R Ilim, resulting in lower total output current. See data sheet for additional information regarding Dynamic Efficiency Scaling. 80% 70% 60% Efficiency (%) R-Ilim 250 R-Ilim 500 R-Ilim 750 50% 40% 30% 20% 10% 0% 0.00 0.50 1.00 1.50 2.00 2.50 3.00 3.50 4.00 4.50 5.00 Power (W) Figure 8. bq51013AEVM-765 Efficiency vs Output Power 6.9 Dynamic Rectifier Control / Dynamic Efficiency Scaling V-rect is the voltage controlled by the global feedback loop, it is LDO input.

You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials. Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please be aware that these devices may be very warm to the touch.
