Buck Switching Regulator IC Positive, Isolation Capable Adjustable 0.596V 1 Output 3A SOT-563, SOT-666 The TPS543021DRLR is a compact, integrated power regulator that converts a wide input voltage (typically from batteries or power rails) into a regulated lower output voltage with high efficiency. It includes internal power switches and control circuitry, simplifying power supply design and reducing external component count. Key Features Topology: Synchronous buck converter Input Voltage Range: ~4.5 V to 28 V Output Voltage: Adjustable (via external resistors) Output Current: Up to 3 A continuous Switching Frequency: ~500 kHz (fixed) Efficiency: High efficiency (up to ~90%+) Quiescent Current: Low, suitable for power-sensitive designs Protection Features: Overcurrent protection (OCP) Thermal shutdown Undervoltage lockout (UVLO) Package & Physical Info Package Type: SOT-563 / VSON (compact, no-lead package) Mounting: Surface Mount (SMT) Packaging: Tape & reel (DRLR suffix) #CommonPartsLibrary #IntegratedCircuit #PowerManagement #Voltage-regulator #Switching-regulator
