FX5545 GXXX XXX PI
Vishay
PIN
DESCRIPTION
SD
Logic low on SD pin shuts down the FunctionPAK completely and decreases current consumption to less than 1A.
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.
Vin
Input supply voltage
Vout
Output voltage
GND
Ground
Rext.
Included inside the package for all fixed output voltage converters. To be added externally for all self-selected output voltages.
