Pin Description
Pin #
Name
Description
A1
V
DD
Analog Supply Input. A 0.1 µF ceramic capacitor is recommended to be placed as close to this
pin as possible. (Figure 1)
B1
V
CON
Voltage Control Analog input. V
CON controls VOUT in PWM mode. (Refer Setting the output
voltage under Application information.) Do not leave floating.
C1
FB
Feedback Analog Input. Connect to the external resistor divider. (Figure 1)
D1
BYP
Bypass. Use this digital input to command operation in Bypass mode. Set BYP low for PWM
operation.
D2
EN
Enable Input. Set this digital input high after Vin >2.7V for normal operation. For shutdown, set
low.
D3
PGND
Power Ground
C3
SW
Switching 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 LM3203.
B3
PV
IN
Power Supply Voltage Input to the internal PFET switch and Bypass FET. (Figure 1)
A3
BYPOUT
Bypass FET Drain. Connect to the output capacitor. (Figure 1) Connect this pin to V
DD when
Bypass mode is NOT required. Do not leave floating.
A2
SGND
Analog and Control Ground
