LM46002PWP 概要

The LM46002 regulator is an easy-to-use synchronous step-down DC/DC converter capable of driving up to 2 A of load current from an input voltage ranging from 3.5 V to 60 V. The LM46002 provides exceptional efficiency, output accuracy and drop-out voltage in a very small solution size. An extended family is available in various load current options and 36-V maximum input voltage in pin-to-pin compatible packages, including LM46001, LM46000, LM43603, LM43602, LM43601 and LM43600. Peak-current-mode control is employed to achieve simple control-loop compensation and cycle-by-cycle current limiting. Optional features such as programmable switching frequency, synchronization, power-good flag, precision enable, internal soft start, extendable soft start, and tracking 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 load efficiency. The family requires few external components. Pin arrangement allows simple, optimum PCB layout. Protection features include thermal shutdown, V_CC undervoltage lockout, cycle-by-cycle current limit, and output short-circuit protection. The LM46002 device is available in the 16-lead HTSSOP / PWP package (6.6 mm × 5.1 mm × 1.2 mm) with 0.65-mm lead pitch.
