The device also incorporates dual N-channel MOSFET power – Adjustable Current Limiting from 75 mA to switches for power distribution systems. This device 2.7 A provides a total power distribution solution, where – ±6% Current-Limit Accuracy at 1.2 A (Typical) precision current limiting and fast protection response – Latch-off Over Current Protection Versions are required. – Reverse Input-Output Voltage Protection A dual 100-m Ω independent power distribution switch limits the output current to a programmable current – Built-In Soft-Start limit threshold between typical 50 mA~2.7 A by using • Integrated Buck DCDC Converter: an external resistor. The current limit accuracy can be – 4.5 V to 28 V Wide Input Voltage Range achieved as tightly as ±6% at typical 1.2 A. The – Maximum Continuous 6-A Output Load nFAULT output asserts low under over-current and reverse-voltage conditions. Current – Feedback Reference Voltage 0.6 V ±1% Constant frequency peak current mode control in the DCDC converter simplifies the compensation and – Fixed 500-kHz Switching Frequency optimizes transient response. Cycle-by-cycle over- – Built-In Internal Soft-Start Time: 1 ms current protection and operating in hiccup mode limit – Cycle-by-Cycle Current Limit MOSFET power dissipation. When die temperature exceeds thermal over loading threshold, the over – Adjustable Current Limit Threshold temperature protection shuts down the device. – Output Over-Voltage Protection – External Clock Synchronization Device Information – Over Temperature Protection ORDER NUMBER PACKAGE BODY SIZE TPS65286RHD VQFN (28) 5 mm x 5 mm 2 Applications • USB Ports and USB Hubs • Digital TV • Computing Power • Laptop Dock • Car Infotainment • Monitoring 4 Simplified Schematic Efficiency 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
