Hi,

Is there any clock IC that can generate 100KHz of 1us or less pulse width to sync multiple UC2825A controllers?

    Below are some general comments related to synchronization of 2 or more PWMs. If a μC is not available to generate the clock signal, option 2 below may be your best choice?

    1. Often accomplished by a μC if available in the system?
    2. A simple clock IC is a basic 555 timer configured as an astable multivibrator shown in Figure 14 of the data sheet here. Also, see related E2E post here.
    3. Set up 2 or more PWMs in "Commander/Responder" configuration such as shown here.
    4. SLUA110, SLUA143, SLUA149 and SLUA257 are TI app notes that discuss PWM SYNC and may offer additional help.

    Regards,

    Steve
