Pin No. Pin Name Pin Function 1 PVCC 5V power supply output. Connect a capacitor (typical 1 F) to AGND. 2 PGOOD Open-drain power good indicator output. 3 A0 LSB of chip address. Tie to GND for 0, pull high for 1. 4 A1 LSB+1 of chip address. Tie to GND for 0, pull high for 1. 5 SCL I2C clock input. 6 SDA I2C data input. 7 SS Soft-start time setting. Connect an external capacitor to GND. 8 FB Feedback voltage input. Connect to output voltage feedback resistor divider. 9 VS Output voltage controlled by VID. 10 AGND Analog ground. 11, 12, 21 (Exposed Pad) PGND Power ground. The exposed pad must be soldered to a large PCB and connected to GND for maximum thermal dissipation. 13, 14, 15 SW Switch node. 16, 17 VIN Power input. Connect to high-side MOSFET Drain. 18 VCC Power input for internal circuit. 19 EN Enable control Input. 20 BOOT Bootstrap supply for high-side gate driver. This capacitor is needed to drive the power switch's gate above the supply voltage. It is connected between the SW and BS pins to form a floating supply across the power switch driver. A 0.1 F capacitor is recommended for use. Marking Information Functional Pin Description Note : Richtek products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes. Ordering Information 2G=YM DNN 2G= : Product Code YMDNN : Date Code RT6203B Package Type QW : WQFN-20L 4x4 (W-Type) (Exposed Pad-Option 1) Lead Plating System G : Green (Halogen Free and Pb Free) UVP Trim Operation L : Latch-off PWM/PSM Mode B : PWM Mode |
