Note**: FX5545G008ADJSM and FX5545G108ADJSM are available only at 1.35V - 4.5V output voltage
PIN DESCRIPTION AND RECOMMENDED BOARD LAYOUT
PIN
DESCRIPTION
SD
Logic low on SD pin shuts down the FunctionPAK completely and decreases current consumption to less than 1 A.
PWM/PSM
Logic high = PWM mode, logic low = PSM mode. In PSM mode synchronous rectification is disabled.
SYNC
Externally controlled synchronization signal. Logic high to low transition forces the clock synchronization.
If not used the pin must be connected to Vin or logic high.
