Description for the TPS65279

TPS65279 is a monolithic dual synchronous buck converter with wide 4.5-V to 18-V operating input voltage range that encompassed most intermediate bus voltage operating off 5-, 9-, 12- or 15-V power bus or battery. The converter with constant frequency peak current mode control is designed to simplify its application while giving the designers options to optimize their usage according to the target applications.

Two bucks in TPS65279 can be paralleled to delivery up to 10-A load current by using current sharing mode, connect ISHARE pin high. Two phase operation in current sharing reduces system filtering capacitance and inductance, alleviates EMI and improves output voltage ripple and noise.

TPS65279 features a dedicated enable pin. An independent soft-start pin provides flexibility in power up programmability. Constant frequency peak current mode control simplifies the compensation and provides fast transient response. Cycle-by-cycle overcurrent protection and hiccup mode operation limit MOSFET power dissipation in short circuit or over loading fault conditions.

Low-side reverse overcurrent protection also prevents excessive sinking current from damaging the converter. TPS65279 also features a light load pulse skipping mode (PSM) controlled by MODE pin configuration.

The TPS65279 is available in a 32-pin thermally-enhanced HTSSOP (DAP) package and 36-pin 6-mm × 6-mm VQFN (RHH) package.

Carrier options

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

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.
