TPS65268-Q1 Triple Step-Down Converter

Texas Instruments TPS65268-Q1 Triple Step-Down Converter incorporates triple-synchronous buck converters with 4 to 8V wide input voltage. The converter in 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 200kHz to 2.3MHz with an external resistor. An 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 conditions for reduced output voltage ripple and improved load transient response. The Texas Instruments TPS65268-Q1 device features over-voltage, over-current, short-circuit, and over-temperature protection.
