The TPS566238PRQFR is a simple, easy-to-use, and high-efficiency 6-A synchronous step-down converter in a QFN 9-pin 1.5mm x 2.0mm package.

TPS566238PRQFR These devices operate over a wider supply input voltage range (3 V to 18 V), provide fast transient response through D-CAP3™ control mode, have good line and load regulation, require no external compensation, and support low-ESR output capacitors.

The TPS566238PRQFR operates in Eco-Mode™ mode to maintain high efficiency during light load operation; with ULQ™ (ultra-low quiescent current) function, it can achieve 50uA quiescent current to extend battery life in low-power applications. The TPS566238PRQFR operates in continuous current mode to maintain low output ripple under all load conditions.

The TPS566238PRQFR soft-start time can be adjusted through the SS pin. The TPS566231P and TPS566238P indicate power-good status through the PG pin.

The TPS566238PRQFR supports up to 98% duty cycle operation and integrates comprehensive hiccup mode OVP, OCP, UVLO, OTP, and UVP protections. They are all available in a 9-pin 1.5mm x 2.0mm HotRod™ package and are specified over the -40°C to 125°C junction temperature range.
