PIN FUNCTION DESCRIPTION
Pin
TSOP−5
Pin
UDFN6
Pin Name Type Description
1 6 EN Analog Input Enable for switching regulators. This pin is active HIGH and is turned off by
logic LOW on this pin.
2 2,4,7
(Note 1)
GND Analog /
Power Ground
This pin is the GND reference for the NFET power stage and the analog
section of the IC. The pin must be connected to the system ground.
3 5 SW Analog Output Connection from power MOSFETs to the Inductor.
4 3 VIN Analog /
Power Input
Power supply input for the PFET power stage, analog and digital blocks. The
pin must be decoupled to ground by a 4.7 mF ceramic capacitor.
5 1 FB Analog Input Feedback voltage from the output of the power supply. This is the input to the
error amplifier.
1. Exposed pad for UDFN6 package, named Pin 7, must be connected to system ground.
