LTM8024
PIN FUNCTIONS PG1/PG2 (Pins L3, K3):
The PGn pin is the open-drain
SYNC (Pin L4):
External Clock Synchronization Input. output of an internal comparator. PGn remains low until Ground this pin for low ripple Burst Mode operation at the FB1 pin is within ±7.5% of the final regulation voltage, low output loads; this will also disable the CLKOUT func- and there are no fault conditions. PGn is pulled low during tion. Apply a DC voltage between 2.8V and 4.0V for spread VIN1 UVLO, VCC UVLO, thermal shutdown, or when RUN1 spectrum modulation. Float the SYNC pin for forced con- or RUN2 are low. tinuous operation without spread spectrum modulation.
TEST (Pin L2):
This pin is used in LTM8024 Apply a clock source to the SYNC pin for synchronization production testing. to an external frequency. The LTM8024 will be in forced continuous mode when an external frequency is applied.
