Pin Descriptions Pin Name Description Application Information 1 SW Switch pin Attaches to the switch node. 2 VIN Source input voltage Input to the regulator. Operates from 4.5V to 42V. 3 BOOT Bootstrap input Provides the gate voltage for the high side NFET. 4 GND System ground Provide good capacitive decoupling between VIN and this pin. 5 RT/SYNC Oscillator frequency adjust pin or frequency synchronization A resistor connected from this pin to GND adjusts the oscillator frequency. This pin can also accept an input for synchronization from an external clock. Pin can be left floating and internal setting will be default to 500 kHz. 6 FB Feedback pin Inverting input to the internal voltage error amplifier. 7 EN Precision enable pin When pulled low regulator turns off. www.national.com 2 |
