MARKING
PART
Input supply voltage. Connect a 10µF ceramic capacitor to power ground.
Input supply voltage for the analog circuitry. Connect to VIN pin.
Regulator enable pin. Keep the EN voltage low in disabled state until VIN settles or is
above 2.5V. Enable the output when driven to high. Shut down the chip and discharge
output capacitor when driven to low. Do not connect directly to VIN or leave this pin
floating.
1ms timer output. At power-up or EN HI, this output is a 1ms delayed Power-Good signal
for the output voltage.
Mode Selection pin. Connect to logic high or input voltage VDD for PWM mode. Connect
to logic low or ground for PFM mode. Connect to an external function generator for
synchronization with the negative edge trigger. Do not leave this pin floating.
Switching node connection. Connect to one terminal of the inductor.
Power ground
Signal ground.
Buck regulator output feedback. Connect to the output through a resistor divider for
adjustable output voltage. For 0.8V output voltage, connect this pin to the output.
No connect.
The exposed pad must be connected to the SGND pin for proper electrical performance.
Place as much vias as possible under the pad connecting to SGND plane for optimal
thermal performance.
