Pin 1 Identification PIN DESCRIPTIONS Pin Name Function 1 BOOST Boost voltage that drives the internal NMOS control switch. A bootstrap capacitor is connected between the BOOST and SW pins. 2 GND Signal and Power ground pin. Place the bottom resistor of the feedback network as close as possible to this pin for accurate regulation. 3 FB Feedback pin. Connect FB to the external resistor divider to set output voltage. 4 EN Enable control input. Logic high enables operation. Do not allow this pin to float or be greater than VIN + 0.3V. 5 VIN Input supply voltage. Connect a bypass capacitor to this pin. 6 SW Output switch. Connects to the inductor, catch diode, and bootstrap capacitor. 2 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated Product Folder Links: LMR12010 |
