Description
No Connect. This pin is not for electrical connection
When set to logic level high, internal circuitry of the device is enabled. When
set to logic level low, the Control and Synchronous FETs are turned off.
TTL level input to MOSFET drivers. When PWM is HIGH, the Control FET is
on and the Sync FET is off. When PWM is LOW, the Sync FET is on and the
Control FET is off.
Supply voltage to internal circuitry.
Voltage Switching Node – pin connection to the output inductor.
Power Ground
Input voltage pin. Connect input capacitors close to this pin.
Floating pin. Externally connect to V SWS2 only.
Floating pin. Externally short to V SWS1 only.
