PRODUCTION DATA
The onboard, 800-kHz oscillator generates the switching frequency by a divide-by-2 circuit. The oscillator can be synchronized to other DCP01B series device circuits or an external source, and is used to minimize system noise.
A watchdog circuit checks the operation of the oscillator circuit. The oscillator can be disabled by pulling the SYNCIN pin low. When the SYNCIN pin goes low, the output pins transition into tri-state mode, which occurs within 2 μs.
