(Adjustable)
Feedback Pin. Receives the feedback voltage from an external
resistive divider across the output.
1
V
OUT
(Fixed
voltage)
Output Voltage Pin. An internal resistive divider divides the output
voltage down for comparison to the internal reference voltage.
2 VSS_CLN Analog Ground Pin.
3 VSS_PWR Power Ground Pin.
4 SW
Switch Pin. Must be connected to Inductor. This pin connects to
the drains of the internal main and synchronous power MOSFET
switches.
5, 6 V
IN_PWR
Power Input Pin. Must be closely decoupled to GND pin with a
4.7ǍF or greater ceramic capacitor.
7 V
IN_CLN
Analog Input Pin. Must be closely decoupled to GND pin with a
4.7ǍF or greater ceramic capacitor.
8 EN
Enable Pin. Minimum 1.2V to enable the device. Maximum 0.4V
to shut down the device. Do not leave this pin floating and
enable the chip after Vin is in the input voltage range.
