TYPICAL APPLICATION AND TECHNICAL NOTES
1)
Fixed Output Voltage Type
VDD
LX
VIN
MODE
PGND
CE
AGND
VOUT
CIN
L
COUT
LOAD
VOUT
L
: 10H LQH3C100K54 (Murata)
COUT : 10F ECSTOJX106R (Panasonic)
CIN
: 10F C3216JB0J106M (TDK)
VFM mode may work with a parasitic diode, but we recommend that VFM mode used with an external diode in be-
tween LX and GND. As for PWM mode, an external diode is not necessary.
