FUNCTION
Input Supply Voltage. Connect to a supply voltage in the 4.5V to 6.5V range. Bypass to PGND with a
2.2μF or larger capacitor, and bypass to GND with a 0.47μF or larger capacitor.
External Synchronous-Rectifier N-MOSFET Gate-Driver Output. Swings between V CC and PGND.
Anticrowbar feature prevents DL from turning on until DH is off and (LX - PGND) < 2V. DL is pulled to
GND in shutdown.
Power Ground
Analog Ground
Dead-Time Delay Programming Input. Connect a resistor from DLY to GND to set the dead-time delay
between when DL falls and when DH rises. Connect DLY to V CC to disable the delay function. See the
Typical Operating Characteristics for R DLY selection.
PWM Input. DH is high when PWM is high; DL is high when PWM is low. Input frequency can be as
high as 1.2MHz for the 10-pin μMAX package and as high as 2MHz for the 10-pin TDFN package.
Enable Input. Drive high to enable output drivers. Drive low to disable output drivers and place the IC
in low-power shutdown mode.
Switching Node and Inductor Connection. Low power supply for the DH high-side gate driver.
Connect to the source of the high-side N-MOSFET and the drain of the low-side N-MOSFET, as well
as the switched side of the inductor.
External High-Side N-MOSFET Gate-Driver Output. Swings between LX and BST. Anticrowbar feature
delays DH from turning on until DL is off. An additional user-programmable delay can be added. DH
is pulled to LX in shutdown.
Boost Flying-Capacitor Connection. Gate-drive power supply for DH high-side gate driver. Connect a
0.47μF or larger capacitor between BST and LX.
Exposed Paddle. Connect to GND.
* 10-pin TDFN only.
