Description for the LMR10530

The LMR10530 regulator is a monolithic, high frequency, PWM step-down DC/DC converteravailable in a 10-pin WSON package. It contains all the active functions to provide local DC/DCconversion with fast transient response and accurate regulation in the smallest possible PCB area.With a minimum of external components, the LMR10530 is easy to use. The ability to drive 3-A loadswith an internal 56-mΩ PMOS switch using state-of-the-art 0.5-µm BiCMOS technology results in thebest power density available. The control circuitry allows on-times as low as 30 ns, thussupporting exceptionally high-frequency conversion over the entire 3-V to 5.5-V input operatingrange down to the minimum output voltage of 0.6 V. Switching frequency is internally set to 1.5 MHzor 3 MHz, allowing the use of extremely small surface mount inductors and capacitors. Even thoughthe operating frequency is high, efficiencies up to 93% are easy to achieve. External shutdown isincluded, featuring an ultra-low stand-by current of 300 nA. The LMR10530 utilizes peakcurrent-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, cycle-by-cycle current limit, frequency foldback, thermal shutdown, and outputovervoltage protection.

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.
