TPS563900
www.ti.com SLVSCC7 – DECEMBER 2013 FEATURES 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 compensation and provides
fast transient response. 1 2 4.5-V to 18-V Wide Input Voltage Range
I2C Controlled 7-Bits VID Programmable
Output Voltage from 0.68 V to 1.95 V with
10-mV Steps for Each Buck; Output Voltage
can also be Set by Resistor Divider
