Page 4 & 5 Added product highlight & schematic for primary side micro-controller dimming application.Updated schematic for secondary side 0-10V dimming application from using dimming transformer to CDM10V. Page 6 Updated pin SQW, ZCD definition and function in Table 2. Page 7 Updated Section 2.1 to introduce ICL8105 supports primary side micro-controller dimming application Section 2.2.4 Updated Figure 9 and description for parameter naming correction from I out min to I out dim min. Added note to indicate V dim max is fixed at 1.72V. Section 2.2.5 Updated description and figure for isolated dimming interface circuitry from using dimming transformer to CDM10V Section 2.2.6 Updated section title from output voltage to output load voltage. Added description to indicate wide output load voltage range condition (more than 2 times of the minimum output load voltage) Section 2.2.7 Updated application note description forthe auto-discharge circuit reference. Section 2.2.9 Added footnote for parameter n ss Section 2.3 Tabled 4: Changed UVLO protection reaction from auto-restart to hardware restart and added note for VCC overvoltage protection reaction to indicate it is configurable. Added startup output undervoltage protection for Vout. Updated Section 2.3.3 description. Section 2.4.1 Added description about ICL8105 excel tool and changed description from 40W form factor board to 40W reference design with CDM10V Section 2.4.2 Updated example value and configuration range of parameters in Table 5. Moved t min demag from fine-tuning section to multimode section in Table 5. Moved parameter Reaction VCCP, a DIM, N DCM MOD GAIN, V DIM MIN & V DIM OFF,from Table 6 to Table 5, Moved parameter V outUV from Table 5 to Table 6, Changed parameter V GD value (from 9V to 10.5V), Changed parameter naming from EN STOP to Debug mode. Added parameter f DCM init and remove parameter EN EPFC. Added selection of Narrow 24.9V for parameter VCC SUPPLY. Page 24 Added section 2.4.3 about Debug mode support. Table 10 Added row with Ta(max) =105 C, Tj(max) =150 C, Added note of Ta(max), Tj(max) limit based on f sw max setting Table 11 Added row with t (typ) = 20.9ns, Added note of t (typ) selection based on f sw max MCLK MCLK Table 15 Added V OCP1 tolerance based on lower V OCP1 setting range. Added V OCP2 selection of 0.6V and changed the range of V OCP1 in the note for V OCP2 selection Table 16 Changed V GD typical value from 9.0V to 10.5V Datasheet 2 Rev. 2.0 2016-08-01
