7 / 12 page TS3300 TS3300 Rev. 1.0 Page 7 PIN FUNCTIONS PIN NAME FUNCTION 1 BI Boost Input. Connect to input source. CBI Connection. 2 CCP Place a 3.3nF capacitor between this pin and GND 3 BEN Boost Enable (active low). To enable the TS3300, connect this to GND. To disable the TS3300, set the voltage to greater than VBI – 50mV. 4 BI FB Boost Input Feedback for Anti-Crush Voltage Setting. The BI FB pin voltage is 392mV. To set the anti-crush voltage, refer to the Applications Information section and to Figure 4. 5 FAC Factory use only. Do not connect to GND or VDD. Leave open. 6 SW EN Connect to REGIN. 7 REG EN Output Load-Switch Logic Input Control (active low). 8 REG FB Connect to REGIN. 9 GND Ground. Connect this pin to the analog ground plane. 10 REGOUT Boost Regulator Load-Switch output. 11 REGIN Boost Regulator Load-Switch input. Connect to BO for use. 12 GND Ground. Connect this pin to the analog ground plane. 13 BO FB Boost Output Feedback. The BO FB pin voltage is 505mV. BO FB coupled with a voltage divider circuit sets the boost regulator output voltage. Refer to Figure 3. 14 BO Regulated output voltage set by resistor network. To set regulated output voltage, refer to Figure 3. CBO connection. 15 LSW Inductor Connection. 16 GND Ground. Connect this pin to the analog ground plane. EP For best electrical and thermal performance, connect exposed paddle to GND. BLOCK DIAGRAM |
