NAME 1 GND G Ground for all circuitry. Reference point for all voltages. 2 MODE/SY NC I This is a multifunction mode control input which is tolerant of voltages up to the input voltage. With this input tied LOW, the device is in Auto PFM mode with automatic transition between PFM and PWM with diode emulation at light load. This mode is recommended when the application requires high efficiency at light load. With this input tied HIGH, the device is in forced PWM mode. The device switches at the internal clock frequency. This mode is recommended when the application requires constant switching frequency across the entire load current. With a valid synchronization signal at this pin, the device switches in forced PWM mode at the external clock frequency and synchronized with it at the rising edge of the clock. Do not float this pin. 3 VIN P Input supply to the regulator. Connect a high-quality bypass capacitor(s) directly to this pin and the GND pin (pin 1). 4 EN I Enable input to the regulator. HIGH = ON, LOW = OFF. This pin can be connected to VIN. Do not float. 5 PGOOD O Open-drain, power-good output. Connect to a suitable voltage supply through a current limiting resistor. HIGH = power is good, LOW = fault. This output terminal is LOW when EN is LOW. 6 VOUT O Output voltage terminal. It is internally connected to one terminal of the integrated inductor. Connect an output filter capacitor from VOUT to GND and place the capacitor as close as possible to the VOUT pin. 7 FB I Feedback input to the regulator. If using the fixed 3.3-V or 5-V options of the device, connect this pin to the positive end of the output filter capacitor (the VOUT node). If using the adjustable output option of the device connect this to the feedback voltage divider and keep this node as small as possible on the board layout. 8 DNC O Do not connect. Leave floating. This pin provides access to the internal VCC voltage of the device. 9 DNC O Do not connect. Leave floating. This pin provides access to the internal BOOT voltage for the high side MOSFET driver. 10 DNC O Do not connect. Leave floating. This pin provides access to the internal SW voltage of the device. Thermal Pad — G This terminal is internally connected to GND and provides a wide thermal connection from the IC to the PCB. Connect to electrical ground plane for adequate heat sinking. G = Ground, I = Input, O = Output, P = Power |
