2. Adjust V
3. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
4. V
5. Standby is disabled for V
6. If not used, Synchronization input must be connected to Ground.
7. Synchronization Pulse Width must be shorter than t
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 V
10. The MC44603A can be shut down by connecting the Soft−Start pin (Pin 11) to Ground.
