2. Adjust VCC above the startup threshold before setting to 12 V.
3. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
4. VC must be greater than 5.0 V.
5. Standby is disabled for VR P Stby < 25 mV typical.
6. If not used, Synchronization input must be connected to Ground.
7. Synchronization Pulse Width must be shorter than tOSC = 1/fOSC.
8. This function can be inhibited by connecting Pin 8 to GND. This allows a continuous current mode operation.
9. This function can be inhibited by connecting Pin 5 to VCC.
10. The MC44603A can be shut down by connecting the Soft−Start pin (Pin 11) to Ground.
