Table 1. Pin Descriptions (continued)
PIN NAME DESCRIPTION APPLICATION INFORMATION
15 SYNC Oscillator UP/DOWN The internal oscillator can be synchronized to an external clock with
synchronization input a frequency 20% lower than the internal oscillator’s free running
frequency. There is no constraint on the maximum sync frequency.
16 UVLO Line Under-Voltage shutdown An external voltage divider from the power source sets the shutdown
comparator levels. The comparator threshold is 2.5V. Hysteresis is
set by an internal current source (20µA) that is switched on or off as
the UVLO pin potential crosses the 2.5V threshold.
