Synchronizing Clock Output. Clock output with a ±10mA peak current drive that can be used to
synchronize an external PWM regulator. CLK/NDRV1 frequency has a 1x, 2x, or 4x ratio. See the
Synchronizing Clock Output section.
Internal Connection. Connect to ground. Internal function.
Oscillator Timing Resistor Connection. Bypass RT with a series combination of a 4.7kΩ resistor and a
1nF capacitor to DGND. Connect a resistor from RT to DGND to set the internal oscillator.
Digital Ground. Connect DGND to ground plane.
Power Ground. Connect PGND to ground plane.
Gate Driver 1. Connect NDRV1 to the gate of the external n-channel FET.
Gate Driver 2. Connect NDRV2 to the gate of the external n-channel FET.
Power-Supply Input. Bypass V
Exposed Pad. Internally connected to DGND. Connect exposed pad to ground plane.
