Pin Name

Pin Function

1

1

LX

Switch Pin. Connect this Pin to inductor and catch diode. Minimize

the track area to reduce EMI.

2

2

GND

Ground Pin

3

3

FB

Feedback Reference Voltage Pin. Series connect a resistor

between Vout and ground as a voltage sense. The feedback

voltage is 1250mV.

4

4

/SHDN

Chip Enable (Active High). Voltage sensing input to trigger the

function of over voltage protection. Note that this pin is high

impedance. There should be a pull low 100k

resistor connected to

GND when the control signal is floating.

5

SS

Softstar pin. Leave SS open to disable the soft-star function.

5

6

Vin

Supply Input Voltage Pin. Bypass 1uF capacitor to GND to reduce

the input noise.
