3 / 19 page Pin Description PIN NUMBER NAME DESCRIPTION APPLICATION INFORMATION LLP-10 TSSOP-14 1 2 SW Switching Node Internally connected to the buck switch source. Connect to the inductor, free-wheeling diode, and bootstrap capacitor. 2 3 BST Boost pin for bootstrap capacitor Connect a 0.022 µF capacitor from SW to this pin. The capacitor is charged from V CC via an internal diode during each off-time. 34 I SEN Current sense The re-circulating current flows through the internal sense resistor, and out of this pin to the free-wheeling diode. Current limit is nominally set at 1.25A. 45 S GND Sense Ground Re-circulating current flows into this pin to the current sense resistor. 5 6 RTN Circuit Ground Ground for all internal circuitry other than the current limit detection. 6 9 FB Feedback input from the regulated output Internally connected to the regulation and over-voltage comparators. The regulation level is 2.5V. 7 10 SS Softstart An internal 11.5 µA current source charges an external capacitor to 2.5V, providing the softstart function. 811 R ON/SD On-time control and shutdown An external resistor from V IN to this pin sets the buck switch on-time. Grounding this pin shuts down the regulator. 912 V CC Output from the startup regulator Nominally regulates at 7.0V. An external voltage (7.5V-14V) can be applied to this pin to reduce internal dissipation. An internal diode connects V CC to V IN. 10 13 V IN Input supply voltage Nominal input range is 8.0V to 75V. 1,7,8,14 NC No connection. No internal connection. www.national.com 3 |
