Description for the LMR10520

The LMR10520 regulator is a monolithic, high frequency, PWM step-down DC/DC converter ina 6-pin WSON package. It provides all the active functions to provide local DC/DC conversion withfast transient response and accurate regulation in the smallest possible PCB area. With a minimumof external components, the LMR10520 is easy to use. The ability to drive 2-A loads with aninternal 150-mΩ PMOS switch results in the best power density available. The world-class controlcircuitry allows on-times as low as 30 ns, thus supporting exceptionally high frequency conversionover the entire 3-V to 5.5-V input operating range down to the minimum output voltage of 0.6 V. TheLMR10520 is internally compensated, so it is simple to use and requires few external components.Even though the operating frequency is high, efficiencies up to 93% are easy to achieve. Externalshutdown is included, featuring an ultra-low stand-by current of 30 nA. The LMR10520 usescurrent-mode control and internal compensation to provide high-performance regulation over a widerange of operating conditions. Additional features include internal soft-start circuitry to reduceinrush current, pulse-by-pulse current limit, thermal shutdown, and output overvoltageprotection.

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.
