Leadis Technology Announces LDS8161 and LDS8141, New LED Drivers Featuring Patent-Pending LED-Sense Temperature Compensation Engine
The LDS8161 and LDS8141 are two new LED drivers featuring its patent-pending LED-Sense(TM) Temperature Compensation engine. These new LED drivers feature allows for direct in-situ monitoring of the WLED junction temperature without the need for an external temperature sensor, thereby optimizing LED brightness and reliability over an LED’s full operating temperature range. Targeted at mobile backlighting applications, the LDS8161/41 drive up to 6 and 4 White LEDs in parallel, respectively, from a single Lithium-Ion battery. The LDS8161/41 introduces a new, straightforward way to address thermal reliability constraints in portable LED backlights. Utilizing LED-Sense(TM), these LED drivers provide real-time monitoring of the LED’s junction temperature. Every few seconds, the LED junction temperature is measured in-situ and the current is adjusted on each LED channel using a programmable current versus temperature de-rating profile…
