SLVSCN0A – JUNE 2014 – REVISED SEPTEMBER 2014 TPS65263, 4.5-to 18-V Input Voltage, 3-A/2-A/2-A Output Current Triple Synchronous
Step-Down Converter With I2C Controlled Dynamic Voltage Scaling
1 Features 3 Description The TPS65263 incorporates triple synchronous buck
converters with 4.5-to 18-V wide input voltage range
that encompassed most intermediate bus voltage
operating off 5-, 9-, 12-, or 15-V power bus or battery.
The converter, with constant frequency peak current
mode, is designed to simplify its application while
giving designers options to optimize the system
according to targeted applications. The device
operates in 600 kHz with 180В° out-of-phase between
buck1 and buck2, buck3 (buck2 and buck3 run in
phase). 1 Operating Input Voltage Range 4.5-to 18-V
Continuous Output Current 3 A/2 A/2 A
I2C Controlled 7-Bits VID Programmable Output
Voltage from 0.68 to 1.95 V With 10-mV Voltage
Step for Each Buck …
