Texas Instruments  LM46001AQPWPRQ1

The LM46001-Q1 regulator is an easy-to-use synchronous step-down DC-DC converter capableof driving up to 1 A of load current from an input voltage ranging from 3.5 V to 60 V. TheLM46001-Q1 provides exceptional efficiency, output accuracy and drop-out voltage in a very smallsolution size. An extended family is available in 0.5-A and 2-A load current options in pin-to-pincompatible packages. Peak current mode control is employed to achieve simple control loopcompensation and cycle-by-cycle current limiting. Optional features such as programmable switchingfrequency, synchronization, power-good flag, precision enable, internal soft start, extendable softstart, 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 loadefficiency. The family requires few external components and pin arrangement allows simple, optimumPCB layout. Protection features include thermal shutdown, VCC undervoltagelockout, cycle-by-cycle current limit, and output short-circuit protection. The LM46001-Q1 deviceis available in the 16-pin HTSSOP (PWP) package (6.6 mm × 5.1 mm × 1.2 mm) with0.65-mm lead pitch. The device is pin-to-pin compatible with LM4360x and LM4600x families. TheLM46001A-Q1 version is optimized for PFM operation and recommended for new designs.
