NAME 1 ENABLE Enables device operation. If ENABLE=logic HIGH, turns on the device. If ENABLE=logic LOW, the device is turned off and MOSFET gates are actively pulled low. An internal 100k Ω pull down resistor will pull the ENABLE pin LOW if left floating. 2 NC Not for electrical connection, connect to floating pad only. 3 VDD Supply Voltage to Gate Drivers and internal circuitry. 4 NC Not for electrical connection, connect to floating pad only. 5 NC Not for electrical connection, connect to floating pad only. 6 VSW Voltage Switching Node – pin connection to the output inductor. 7 VSW Voltage Switching Node – pin connection to the output inductor. 8 VSW Voltage Switching Node – pin connection to the output inductor. 9 VSW Voltage Switching Node – pin connection to the output inductor. 10 VSW Voltage Switching Node – pin connection to the output inductor. 11 VSW Voltage Switching Node – pin connection to the output inductor. 12 VIN Input Voltage Pin. Connect input capacitors close to this pin. 13 VIN Input Voltage Pin. Connect input capacitors close to this pin. 14 VIN Input Voltage Pin. Connect input capacitors close to this pin. 15 VIN Input Voltage Pin. Connect input capacitors close to this pin. 16 VIN Input Voltage Pin. Connect input capacitors close to this pin. 17 VIN Input Voltage Pin. Connect input capacitors close to this pin. 18 BOOT_R Bootstrap capacitor connection. Connect a minimum 0.1µF 16V X5R, ceramic cap from BOOT to BOOT_R pins. The bootstrap capacitor provides the charge to turn on the Control FET. The bootstrap diode is integrated. 19 BOOT 20 NC Not for electrical connection, connect to floating pad only. 21 NC Not for electrical connection, connect to floating pad only. 22 PWM Pulse Width modulated 3-state input from external controller. Logic Low sets Control FET gate low and Sync FET gate high. Logic High sets Control FET gate high and Sync FET gate Low. Open or High Z sets both MOSFET gates low if greater than the 3-State Shutdown Hold-off Time (t3HT) 23 PGND Power Ground 4 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated |
