Definition
1, 2
VPWR
Positive Supply
Voltage Input
This is the most positive power supply input. The load connects between this pin
and the VOUT pin.
3
RCLA
Classification Resistor
Connect a resistor between RCLA and VIN to select the class of the PD.
4
UVLO
Undervoltage Lookout
Used to adjust the undervoltage lookout threshold voltage, connected to VIN to use
the default threshold voltage.
5
TEST1
Test pins
Connect to VIN in application mode.
6
TEST2
7
FREQ
Frequency Adjustment
Adjusts the internal oscillator frequency by connecting a resistor between FREQ
and VIN.
8
ILIM
Inrush Current Limit
Used to adjust the inrush current limit of the isolation switch, add a resistor
between ILIM and VIN.
9
VIN
Negative Supply Voltage
This is the most negative power supply input.
10
VIN
11, 12
VOUT
Output Voltage
This pin is the drain of the internal Power MOSFET (high current path).
13
VOUT
Output Voltage
This pin is the drain of the internal Power MOSFET (low current path).
14
RESET
RESET Output
(active low)
This is an active-low RESET output signal. This pin is referenced to VOUT.
15
SS
Soft Start Input
Connect an external capacitor to SS. The internal current source charges the
capacitor and generates a soft-start ramp.
16
COMP
Compensation Pin
COMP is the output of the error amplifier and is available for feedback
compensation. COMP is pulled-up by an internal 5.0 k
Ω resistor to 5.0 V.
17
FB
Feedback Input
This is the inverting input of the error amplifier. In non-isolated applications it’s
connected to the secondary output through a resistor divider.
18
CS
Current Sense
The current sense pin CS senses a voltage that is proportional to the current
through the sense resistor.
19
GATE
Gate Driver Output
GATE drives the gate of the external power MOSFET. GATE sources and sinks
up to 1.0 A.
20
VDD
VDD Output
VDD mainly supplies the gate of the external power MOSFET. Connect a capacitor
from VDD to VOUT.
