32. INPUT UNDERVOLTAGE LOCKOUT

At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage above

the undervoltage lockout turn-on threshold.

35. SYNCHRONIZATION

The module switching frequency can be synchronized to a signal with an external frequency within a specified range. Synchronization can be done by using

the external signal applied to the SYNC pin of the module as shown in Fig. 45, with the converter being synchronized by the rising edge of the external signal.

The Electrical Specifications table specifies the requirements of the external SYNC signal. If the SYNC pin is not used, the module should free run at the

default switching frequency. If synchronization is not being used, connect the SYNC pin to GND.
