Application: Application testing has shown that the behavior of the ZLLS1000 version 4 in selected parameters (below) is identical to the LED typical application in Version 3. Results using the ZXLD1366EV1 evaluation board: 1) 30V single LEDÆ the diode is in blocking 2) 18V 4LEDs Æ the diode is mainly conducting ILED [mA] 200 500 1000 30V single LED ( blocking) Version 4 Version 3 67.40% 67.10% 67.30% 68.20% 60.00% 61.20% 18V 4LEDs (Conducting) Version 4 Version 3 91% 91% 90.10% 90.50% 85.27% 86.10% Differences: Differences between version 3 and version 4 of the ZLLS1000 datasheet are as follows: From (Version 3): From (Version 3 cont’d): To (Version 4): To (Version 4 cont’d): All graphs in version 4 have been updated to reflect revised typical performance. Details of Change to ZLLS2000 Datasheet Specification Updates to the manufacturing environments have led to the necessity to increase specification limits for certain parameters to aid manufacturability and capability. A small increase in the typical performance is seen for lower currents. For operating currents from 500mA and higher, the Voltage drop across the forward bias diode is lower thus minimizing power dissipation. The reverse bias leakage is reduced by 50%. This further implies that there is a reduction in power dissipation and an increase in maximum operating temperature during significant reverse bias duty. Application: Application testing has shown that the behavior of the ZLLS2000 version 5 in selected parameters (below) is identical to the LED typical application in Version 4. Results using the ZXLD1322 evaluation board: 1) Data from 2 LED @350mA with Vin @ 8V DS version Efficiency Version 4 76.1% Version 5 75.3% Differences: Differences between version 4 and version 5 of the ZLLS2000 datasheet are as follows: From (Version 4): To (Version 5): All graphs in version 5 have been updated to reflect revised typical performance. Details of Change to ZLLS410 Datasheet Specification Updates to the manufacturing environments have led to the necessity to increase specification limits for certain parameters to aid manufacturability and capability. Significant enhancements to the device performance have been made including (a) improvement to the device performance with respect to reverse bias leakage current improving reverse power, (b) an improvement in high current Vf performance over previous version of devices, (c) improvement in SOA and maximum ambient operating temperature for a wide range of duty cycle, and (d) an increase in very low current Vf performance over previous version of devices. Differences: Differences between version 1 and version 2 of the ZLLS410 datasheet are as follows: From (Version 1): To (Version 2): All graphs in version 2 have been updated to reflect revised typical performance.
