TPS62865/67 4 A/6 A Synchronous Step-Down Converters

Texas Instruments' 2.4 V to 5.5 V input converters utilize DCS-control™ technology for fast transient response

Image of Texas Instruments' TPS62867 6 A Synchronous Step-Down ConverterTexas Instruments' TPS62865 and TPS62867 are high-frequency synchronous step-down converters that provide an efficient, flexible, and high power density solution. At medium to heavy loads, the converters operate in PWM mode and automatically enter power-save-mode operation at light-load to maintain high efficiency over the load current range. The devices can be forced in PWM mode operation to minimize output voltage ripple.

The DCS-control architecture helps achieve excellent load transient performance and tight output voltage accuracy. These converters feature a power-good signal and an internal soft-start circuit. The devices can operate in 100% mode. For fault protection, the devices incorporate a HICCUP short-circuit protection and thermal shutdown.
