Pin assignment Pin Description(s) Pin No Pin Name Description Connect a bootstrap capacitor of 0.1F between this terminal and SW terminal. 1 BOOT The voltage of this capacitor is the gate drive voltage of the high-side MOSFET. Power supply terminal for the switching regulator and control circuit. 2 VIN Connecting a 10F and 0.1F ceramic capacitor is recommended. Turning this terminal signal low-level (0.8V or lower) forces the device to enter the shut 3 EN down mode. Turning this terminal signal high-level (2.5V or higher) enables the device. This terminal must be terminated. 4 AGND Ground terminal for the control circuit. Inverting input node for the gm error amplifier. 5 FB See page 18 on how to calculate the resistance of the output voltage setting. Output of gm error amplifier, and input of PWM comparator. Connect phase 6 COMP compensation components to this pin. See page 20 on how to calculate the resistance and capacitance for phase compensation. 7 PGND Ground terminal for the output stage of the switching regulator. 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 8 SW terminal and BOOT terminal. In addition, connect an inductor considering the direct current superimposition characteristic. Exposed pad. Connecting this to the internal PCB ground plane using multiple vias - E-Pad provides excellent heat dissipation characteristics. www.rohm.com TSZ02201-0J3J0AJ00650-1-2 2015 ROHM Co., Ltd.
