Description
1
PGND
Ground for the output section
2
VIN
Input pin
This pin is placed in the standby state if VENB = low. Standby current is 1 μA or less.
3
EN
Enable pin
This pin is connected to an on-chip CMOS inverter. When EN
≥ 3.5 V (@VIN = 5 V), the control logic is
allowed to operate and thus enable the switching operation of the output section.
4
SGND
Ground for the control logic
5
N.C.
No-connect
6
N.C.
No-connect
7
VFB
Feedback pin
Output voltage is set to 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V (typ.) internally.
8
LX
Switch pin
This output is connected to the high-side P-channel MOSFETs and low-side N-channel MOSFET.
0.8V (typ.)
