DESCRIPTION
TPS652510 is a power management IC with three step-down buck converters. Both high-side and low-side MOSFETs are integrated to provide fully synchronous conversion with higher efficiency. The converters are designed to simplify its application while giving the designer the option to optimize their usage according to the target application.

FEATURES
• Wide Input Supply Voltage Range: 4.5 V - 16 V
• 0.8-V, 1% Accuracy Reference
• Continuous Loading: 3 A (Buck1), 2 A (Buck2 and 3)
• Maximum Current: 3.5 A (Buck 1), 2.5 A (Buck2 and 3)
• Synchronous Operation, 300-kHz – 2.2-MHz Switching Frequency Set By External Resistor
• External Enable Pins With Built-In Current Source for Easy Sequencing
• External Soft Start Pins
• Adjustable Cycle-by-Cycle Current Limit Set by External Resistor
• Current-Mode Control With Simple Compensation Circuit
• Automatic Low Pulse Skipping (PSM) Power Mode, Allowing for an Output Ripple Better than 2%
• Support Pre-Biased Outputs
• Power Good Supervisor and Reset Generator
• Small, Thermally Efficient 40-Pin 6-mm x 6-mm RHA (QFN) package
• -40°C to 125°C Junction Temperature Range
