PIN DESCRIPTION
The supply input pin is a terminal for an unregulated input voltage source. It is
required to place the input capacitor nearby the VIN pin and PGND.
An external resistor from RON to VIN pin sets the on-time and frequency of the
application. The value range of the resistor is from 25kΩ to 124kΩ.
The enable input pin is internally connected to the precision enable comparator
and the rising threshold is at 1.18V. Maximum recommended input level is 6.5V.
The analog ground pin is the reference point for all stated voltages and must be
connected to PGND.
For the soft-start function there is an internal 8μA current source which charges
an external capacitor to generate the soft-start.
The feedback pin is internally connected to the regulation circuitry, the over-
voltage and short-circuit comparators. The regulation reference point is 0.8V at
this input pin. Connect the feedback resistor divider between the output and
AGND to set the output voltage.
The output voltage pin is connected to the internal inductor. For the best stability
and operation connect the output capacitor between this pin and PGND.
Exposed Pad – Main node for switch current of internal LS-MOSFET. Used as
heat sink for power dissipation during operation. Must be electrically connected
to pin 4.
