1. Describe

The TPS65266-1RHBT integrates 3 channels of high-efficiency synchronous buck converters for Apps that close the adapter or battery The input voltage is below 6 V. Step-Down DC/DC Converter Integrated Power Supply MOSFETs for optimized power efficiency and Reduce external component count. peak Current mode control simplifies compensation and Fast transient response. High clock frequency allows Smaller and lower value inductors and capacitors. External compensation supports optimized loop compensation and fast transient response. in the light Buck converter operates in PSM mode under load Reduced input power mode system. Cycle-by-Cycle Over-Current Limit Hiccup Mode Limits MOSFET Power Dissipation short circuit or overload fault conditions. TPS65266-1RHBT with power good monitor Circuitry that monitors all converter outputs. this The PGOOD pin is valid after the output voltage Each channel is conditioned and sequenced complete. When continuous severe overload or short circuit increase the power dissipation of the buck converter, An internal thermal protection circuit shuts down the device to prevent damage. recovery from heat Automatic shutdown after device cools down fully.
