The LM46002-Q1 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-Q1 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. 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 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, VCC undervoltage lockout, cycle-by-cycle current limit, and output short-circuit protection. The LM46002A-Q1 version is optimized for PFM operation and recommended for new designs. The LM46002-Q1 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.
