2 / 7 page TS19730CX6 Taiwan Semiconductor 2 Version: B1601 THERMAL PERFORMANCE PARAMETER SYMBOL LIMIT UNIT Thermal Resistance - Junction to Case RӨJC 106.6 °C/W Thermal Resistance - Junction to Ambient RӨJA 220 °C/W Note: RӨJA is the sum of the junction-to-case and case-to-ambient thermal resistances. The case thermal reference is defined at the solder mounting surface of the drain pins. RӨJA is guaranteed by design while RӨCA is determined by the user’s board design. RӨJA shown below for single device operation on FR-4 PCB in still air. Thermal Resistance is specified with the component mounted on a low effective thermal conductivity test board in free air at TA=25°C. RECOMMENDED OPERATING CONDITIONS (Note 3) PARAMETER SYMBOL CONDITIONS UNIT Power Supply Pin VCC 33 V CL Voltage to GND VCL -0.3 to 5 V OUT Voltage to GND VOUT -0.3 to 19 V CS Voltage to GND VCS -0.3 to 5 V COM Voltage to GND VCOM -0.3 to 5 V Operating Junction Temperature Range TJ -40 to +125 °C Operating Ambient Temperature Range TOPA -40 to +85 °C ELECTRICAL SPECIFICATIONS (V CC = 18V, TA = 25°C unless otherwise noted) PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNIT Supply Voltage Start-up Current VCC(ST) VCC= VUVLO(on) -1V -- 45 -- μA Operating Current IOPA With 1nF load on out pin -- 2.1 2.6 mA UVLO(off) VUVLO(off) 7 8 9 V UVLO(on) VUVLO(on) 16 17.5 19 V OVP Level on VCC Pin VOVP 29 31 33 V Voltage Feedback Feedback Reference Voltage VFB 0.196 0.2 0.204 V Transconductance gm -- 58 -- μS Output Sink Current IO-SINK -- 5.8 -- μA Output Source Current IO-SOURCE -- 5.8 -- μA Current Sensing Open Loop Voltage VOLP CS Pin Open -- 5 -- V Leading-Edge Blanking Time tLEB -- 400 -- ns Delay to Output tDELAY -- 100 -- ns Current Limit CL Limit Voltage VOCP -- 0.3 -- V Switching Frequency Start Frequency fSTR -- 4.5 -- kHz |
