Voltage divider provides adjustable off mode detection threshold − 4 3 3 VMIN Minimum output voltage adjustment 4 − 4 − ISNS Current sensing input for output current regulation, connect it to shunt resistor in ground branch. − − 5 4 LED PWM LED driver output. Connected to LED cath- ode with current define by external serial resist- ance − − − 6 FBC Output of current sinking OTA amplifier or amplifi- ers driving feedback optocoupler’s LED. Connect here compensation network (networks) as well. − − − 5 ON/OFF OFF mode current sink. This output keeps primary control pin at low level in off mode. 3 3 6 − DRIVE Combination of FBC and ON/OFF pins ABSOLUTE MAXIMUM RATINGS Rating Symbol Value Unit Input Voltage VCC −0.3 to 40 V DRIVE, ON/OFF, FBC, LED Voltage VDRIVE, VONOFF, VFBC, VLED −0.3 to VCC + 0.3 V VSNS, ISNS, OFFDET, VMIN Voltage VSNS, VISNS, VOFFDET, VMIN −0.3 to 10 V LED Current ILED 10 mA Thermal Resistance − Junction−to−Air (Note 1) NCP4353A NCP4353B NCP4354A NCP4354B RqJA 315 324 260 277 °C/W Junction Temperature TJ −40 to 150 °C Storage Temperature TSTG −60 to 150 °C ESD Capability, Human Body Model (Note 2) ESDHBM 2000 V ESD Capability, Machine Model (Note 2) ESDMM 250 V Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. 50 mm2, 1.0 oz. Copper spreader. 2. This device series incorporates ESD protection and is tested by the following methods: ESD Human Body Model tested per JESD22−A114F ESD Machine Model tested per JESD22−A115C Latchup Current Maximum Rating tested per JEDEC standard: JESD78D. |
