Description
Power Input.
Frequency Select. High = 1.2 MHz, low = 600 kHz.
Enable. Enable input with precision thresholds.
Synchronize. This pin is used to synchronize the device to an external 600 kHz to 1.2 MHz clock or forces
PWM mode when it is held high. SYNC held low forces automatic PWM/PSM operation.
Feedback. This pin provides feedback from the output.
Power Good. PG is an open-drain output.
Switch. This pin serves as the connection from the power MOSFETs to the inductor.
Power Ground.
Exposed Pad. The exposed pad on the bottom of the package enhances the thermal performance and is
electrically connected to ground inside the package. The exposed pad must be connected to the ground
plane on the circuit board for proper operation.
