Pin Description
Pin Name Function
1-2 SW Switched-node connection, which is connected to the source of the internal high-side
MOSFET.
3-5 PV
IN
Main power supply input pin. Connected to the drain of the internal high-side MOSFET.
6V
CB
Bootstrap capacitor connection for high-side gate drive.
7AV
IN
Input voltage for control and drive circuits.
8 SD(SS)
Shutdown and Soft-start control pin. Pulling this pin below 0.3V shuts off the regulator. A
capacitor connected from this pin to ground provides a control ramp of the input current.
Do not drive this pin with an external source or erroneous operation may result.
9 FB Output voltage feedback input. Connected to the output voltage.
10 COMP Compensation network connection. Connected to the output of the voltage error amplifier.
11 L
DELAY
A capacitor between this pin to ground sets the delay from when the output voltage
reaches 80% of its nominal to when the undervoltage latch protection is enabled.
12 LDR Low-side FET gate drive pin.
13 GND Power ground.
14-16 PV
IN
Main power supply input pin. Connected to the drain of the internal high-side MOSFET.
