Pin Name
Pin Function
Feedback Voltage Input. This pin receives the feedback voltage from
a resistive divider connected across the output.
Power Ground.
Enable Control Input. A voltage on this pin above 1.25V enables the
converter into normal mode; forcing this pin below 0.3V shuts down
the IC, reducing quiescent current to 3A.
An internal 2A current pulls up enable pin for automatic startup.
High-Side Peak Current Set Pin. A resistor from this pin to GND sets
the high-side peak current limit. Leave floating for the maximum
peak current, 225mA. Short this pin to GND for the minimum peak
current, 50mA. A 1A current is sourced out of this pin.
Input Supply Voltage. Must bypass with a suitably large ceramic
capacitor.
Switch Node. Connect The Switching Node To External Inductor.
Power Good Open Drain Output. Asserts low if output voltage is low
due to OTP, UVP, UVLO, EN shutdown or during soft-start.
Analog Ground.
