LB1966M

No. 6215-3/4

Sample Application Circuit

5/12V power supply (3.8 to 17V)

Precautions

• Wiring layout for IN– and OUT1 must be designed to prevent interference. (If oscillation occurs for example when

output phase is switched, connect a capacitor with 0.1

µF or less between IN– and IN+ pins.)

• If CT pin is connected to GND, the lockup protection and restart functions are disabled.

• In a circuit configuration as shown above, a power supply/GND reverse connection will cause a current to flow as

follows: GND -> OUT -> coil -> power supply. The magnitude of this current is limited by the coil resistance. If it

is less than 500 mA, the IC will not be destroyed. If required, insert a diode between VCC and the coil.
