Note:
The actual physical placement of the package marking will vary from part to part. The package marking “X” designates the date code. “V” is a NSC internal
code for die traceability. Both will vary considerably. “S” designates the device type as switcher device. “34” identifies the device part number/option.
Pin Descriptions
Pin #
Name
Description
A1
PV
IN
Power Supply Voltage Input.
B1
EN
LDO
LDO Enable Input. Set this digital input high to turn on LDO (EN pin must also be set high). For shutdown,
set low.
C1
FB
Feedback Analog Input. Connect to the output at the output filter capacitor.
C2
V
CON
Voltage Control Analog input. V
CON controls VOUT in PWM mode.
C3
LDO
LDO Output Voltage.
B3
SGND
Analog and Control Ground.
A3
PGND
Power Ground.
A2
SW
Switch node connection to the internal PFET switch and NFET synchronous rectifier. Connect to an
inductor with a saturation current rating that exceeds the maximum Switch Peak Current Limit specification
of the LM3207.
B2
EN
PWM enable Input. Set this digital input high for normal operation. For shutdown, set low.
