Description for the LM46002

The LM46002 regulator is an easy-to-use synchronous step-down DC/DC converter capable ofdriving up to 2 A of load current from an input voltage ranging from 3.5 V to 60 V. The LM46002provides exceptional efficiency, output accuracy and drop-out voltage in a very small solutionsize. An extended family is available in various load current options and 36-V maximum inputvoltage in pin-to-pin compatible packages, including LM46001, LM46000, LM43603, LM43602, LM43601and LM43600. Peak-current-mode control is employed to achieve simple control-loop compensation andcycle-by-cycle current limiting. Optional features such as programmable switching frequency,synchronization, power-good flag, precision enable, internal soft start, extendable soft start, andtracking provide a flexible and easy-to-use platform for a wide range of applications.Discontinuous conduction and automatic frequency reduction at light loads improve light loadefficiency. The family requires few external components. Pin arrangement allows simple, optimum PCBlayout. Protection features include thermal shutdown, VCC undervoltagelockout, cycle-by-cycle current limit, and output short-circuit protection. The LM46002 device isavailable in the 16-lead HTSSOP / PWP package (6.6 mm × 5.1 mm × 1.2 mm) with 0.65-mm lead pitch.

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.
