TPS563900 - Texas Instruments

TPS563900 3.5-A/3.5-A Dual Synchronous Step-Down Converter

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 compensation and provides fast transient response. External feedback resistors can be used to.
