Description for the TPS65283-1

The TPS65283, TPS65283-1 in thermally-enhanced 4-mm × 4-mm VQFN package is a full featured
4.5- to 18-V Vin, 3.5-A/2.5-A output current synchronous step down DC-DC converter, which is optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs. The device also incorporates one N-channel MOSFET power switches for power distribution systems. This device provides a total power distribution solution, where precision current limiting and fast protection response are required.

The 60-mΩ independent power distribution switch limits the output current to a programmable current limit threshold by using an external resistor. The current limit accuracy can be achieved as tight as ±10% at typical 1.25 A. The nFAULT output asserts low under overcurrent and reverse-voltage conditions.

Constant frequency peak current mode control in DC-DC converter simplifies the compensation and optimizes transient response. Cycle-by-cycle overcurrent protection and operating in hiccup mode limit MOSFET power dissipation during buck output short circuit or over loading conditions. When die temperature exceeds thermal over loading threshold, the overtemperature protection shuts down the device.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
