Two current sink regulators of high current-matching capability are integrated in the TPS61162A,TPS61163A to support dual LED strings connection and to improve the current balance and protect the LED diodes when either LED string is open or short. The TPS61162A, TPS61163A has integrated all of the key function blocks to power and control up to 20 white LED diodes. It includes a 1.5-A, 40-V boost converter, two current-sink regulators, and protection circuit for overcurrent, overvoltage, and thermal shutdown protection. In order to provide high brightness backlighting for large size or high resolution smart phone panels, more and more white LED diodes are used. Having all LED diodes in a string improves overall current matching; however, the output voltage of a boost converter will be limited when input voltage is low, and normally the efficiency will drop when output voltage goes very high. Thus, the LED diodes are arranged in two parallel strings. 7.2 Functional Block Diagram 8 Submit Documentation Feedback Copyright © 2013–2015, Texas Instruments Incorporated Product Folder Links: TPS61162A TPS61163A |
