Pin Assignment Pin Descriptions Pin No. Pin Name Function 1 PGND Ground pins for the output stage of the switching regulator. This pins supply power to the control circuit and the output stage of the switching regulator. 2 VIN Connecting a 10 F and a 0.1F ceramic capacitor is recommended. 3 AGND Ground pin for the control circuit. An inverting input node for the gm error amplifier. 4 FB See page 14 for how to calculate the resistance of the output voltage setting. An input pin for the switch current comparator and an output pin for the gm error amplifier. Connect a 5 COMP frequency phase compensation component to this pin. See page 14 for how to calculate the resistance and capacitance for phase compensation. Turning this pin signal low (0.8 V or lower) forces the device to enter the shutdown mode. Turning this 6 EN pin signal high (2.0 V or higher) enables the device. This pin must be terminated. 7 SW Switch nodes. These pins are connected to the drain of Pch MOSFET and the drain of Nch MOSFET. 8 www.rohm.com TSZ02201-0J3J0AJ00540-1-2 2013 ROHM Co., Ltd.
