UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
|1||CB||P||Bootstrap capacitor connection for high-side FET driver. Connect a high quality 100-nF capacitor from this pin to the SW pin.|
|2||GND||G||Power ground terminals, connected to the source of low-side FET internally. Connect to system ground, ground side of CIN and COUT. Path to CIN must be as short as possible.|
|3||FB||A||Feedback input to the convertor. Connect a resistor divider to set the output voltage. Never short this terminal to ground during operation.|
|4||EN||A||Precision enable input to the convertor. Do not float. High = on, Low = off. Can be tied to VIN. Precision enable input allows adjustable UVLO by external resistor divider.|
|5||VIN||P||Supply input terminal to internal bias LDO and high-side FET. Connect to input supply and input bypass capacitors CIN. Input bypass capacitors must be directly connected to this pin and GND.|
|6||SW||P||Switching output of the convertor. Internally connected to source of the high-side FET and drain of the low-side FET. Connect to power inductor.|
