The TPS566231and TPS566238 are simple, easy to use, high-efficiency, 6-A synchronous buck converters in QFN9-pin 1.5-mm x 2.0-mm package.
The devices operate with wider supply input voltage ranging from 3 V to 17 V. They useDCAP3™ control mode to provide a fast transient response, good line, load regulation, norequirement for external compensation, and support low ESR output capacitors.
TPS566231 operates in Eco-Mode, which maintains high efficiency during light loadoperation. One of the key features of the TPS566231 is its ULQ (Ultra Low Quiescent) to enablelow-bias current. This feature is extremely beneficial for long battery life in low poweroperation.
TPS566238 operates in continuous current mode, which maintains lower output ripple duringall load conditions.
TPS566231 and TPS566238 can support upto 98% duty cycleoperation. They provide complete protection OVP, OCP, UVLO, OTP and UVP with auto-retry.
The TPS566231 and TPS566238 are available in a 9-pin 1.5-mm x 2.0-mmHotRod™ package and the junction temperature is specified from-40oC to 125oC.
