2 / 16 page  RT8015B 2 DS8015B-04 March 2011 www.richtek.com Functional Pin Description Pin No. WDFN -10L 3x3 SOP-8 (Exposed Pad) Pin Name Pin Function 1 1 SHDN/RT Oscillator Resistor Input. Connecting a resistor to ground from this pin sets the switching frequency. Forcing this pin to VDD causes the device to be shut down. 2 2 GND Signal Ground. All small signal components and compensation components should connect to this ground, which in turn connects to PGND at one point. 3, 4 3 LX Internal Power MOSFET Switches Output. Connect this pin to the inductor. 5 4 PGND Power Ground. Connect this pin close to the negative terminal of CIN and COUT. 6 5 PVDD Power Input Supply. Decouple this pin to PGND with a capacitor. 7 6 VDD Signal Input Supply. Decouple this pin to GND with a capacitor. Normally VDD is equal to PVDD. 8 -- PGOOD Power Good Indicator. This pin is open drain logic output that is pulled to ground when the output voltage is not within ±12.5% of regulation point. 9 7 FB Feedback Pin. This pin receives the feedback voltage from a resistive divider connected across the output. 10 8 COMP Error Amplifier Compensation Point. The current comparator threshold increases with this control voltage. Connect external compensation elements to this pin to stabilize the control loop. 11 -- (Exposed Pad) No Internal Connection. The exposed pad must be soldered to a large PCB and connected to GND for maximum power dissipation. -- 9 GND The exposed pad must be soldered to a large PCB and connected to GND for maximum power dissipation.
