Terminal for setting the soft start time. The rise time of the output voltage can be specified by 4 SS connecting a capacitor to this terminal. Refer to page.17 for how to calculate the capacitance. 5 GND Ground terminal for the output stage of the switching regulator and the control circuit Switch node. This terminal is connected to the source of the high-side MOSFET and drain of the low-side MOSFET. Connect a bootstrap capacitor of 0.1F between this terminal and 6 SW BOOT terminal. In addition, connect an inductor considering the direct current superimposition characteristic. Connect a bootstrap capacitor of 0.1F between this terminal and SW terminal. 7 BOOT The voltage of this capacitor is the gate drive voltage of the high-side MOSFET. Power supply terminal for the switching regulator. 8 VIN Connecting a 20F(10F2) and 0.1F ceramic capacitor to ground is recommended. A backside heat dissipation pad. Connecting to the internal PCB ground plane by using - FIN multiple via provides excellent heat dissipation characteristics. www.rohm.co.jp TSZ02201-0J3J0AC00490-1-2 2013 ROHM Co., Ltd.
