Description for the LM43601

The LM43601 regulator is an easy to use synchronous step-down DC-DC converter capable ofdriving up to 1 A of load current from an input voltage ranging from 3.5 V to 36 V (42 Vtransient). The LM43601 provides exceptional efficiency, output accuracy, and dropout voltage in avery small solution size. An extended family is available in 0.5-A, 2-A and 3-A load currentoptions in pin-to-pin compatible packages. Peak-current-mode control is employed to achieve simplecontrol-loop compensation and cycle-by-cycle current limiting. Optional features such asprogrammable switching frequency, synchronization, power-good flag, precision enable, internal softstart, extendable soft start, and tracking provide a flexible and easy-to-use platform for a widerange of applications. Discontinuous conduction and automatic frequency modulation at light loadsimprove light load efficiency. The family requires few external components and pin arrangementallows simple, optimum PCB layout. Protection features include thermal shutdown,VCC undervoltage lockout, cycle-by-cycle current limit, and outputshort-circuit protection. The LM43601 device is available in the 16-leaded HTSSOP (PWP) package(6.6 mm × 5.1 mm × 1.2 mm) with 0.65-mm lead pitch. This device is pin-to-pin compatible withLM46000, LM46001, LM46002, LM43600, LM43602, and LM43603.

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.
