Notice
-
• Take care not to cause interference due to wiring of IN and OUT1.
• In an application of connecting the CT pin to GND, lock protection and restart function are not effective.
• With reverse power - GND connection in the above application figure, the current restricted by the coil resistance
flows from GND → OUT → coil → power supply. IC breakage does not occur if the current value is 500mA or less.
If necessary, insert Di between V
and coil.
