Description
Input voltage pin. Connect input capacitors close to this pin.
Voltage Switching Node – pin connection to the output inductor.
Power Ground
Supply voltage to internal circuitry.
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.
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.
No Connection, can be left floating. (Note A)
Notes:
A. It is recommended to connect PIN 7 and 8 to PIN 1 on PCB to reduce thermal resistance.
