TPS563900 Description
The TPS563900 device is a monolithic dualsynchronous buck converter with a wide 4.5-V to 18V operating input-voltage range that can operate in 5-, 9-, 12-, or 15-V bus voltages and battery chemistries. Constant-frequency peak-current mode control simplifies the loop pensation and provides fast transient response. External feedback resistors can be used to set the initial start-up voltage for each buck converter in...
