The TPS65268-Q1 device incorporates triple-synchronous buck converters with 4- to 8-V
wide input voltage. 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 switching frequency of the converters is adjustable from 200 kHz to 2.3 MHz with
an external resistor. Operation that is 180° out-of-phase between BUCK1 and BUCK2, and BUCK3 (BUCK2
and BUCK3 run in phase) minimizes the input filter requirements.
Each buck converter in the TPS65268-Q1 device operates in forced continuous-current mode
(FCCM) at light load condition for reduced output voltage ripple and improved load transient
response.
The TPS65268-Q1 device features overvoltage, overcurrent, short-circuit, and
overtemperature protection.
