Texas Instruments  LM46002AQPWPRQ1

The LM46002-Q1 regulator is an easy-to-use synchronous step-down DC-DC converter capableof driving up to 2 A of load current from an input voltage ranging from 3.5 V to 60 V. TheLM46002-Q1 provides exceptional efficiency, output accuracy and drop-out voltage in a very smallsolution size. An extended family is available in various load-current options and 36-V maximuminput voltage. The device is pin-to-pin compatible package with LM4360x and LM4600x family.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 LM46002A-Q1 versionis optimized for PFM operation and recommended for new designs. The LM46002-Q1 device is availablein the 16-lead HTSSOP (PWP) package (6.6 mm × 5.1 mm × 1.2 mm) with 0.65-mm lead pitch.
