The LM43602 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 36 V (42-V absolute maximum). The LM43602 provides exceptional efficiency, output accuracy, and dropout voltage in a very small solution size. An extended family is available in 0.5-A, 1-A, and 3-A load current options in pin-to-pin compatible packages. 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 modulation at light loads improve light-load efficiency. The family requires few external components and terminal 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 LM43602 device is available in a 16-lead HTSSOP package (5.1 mm × 6.6 mm × 1.2 mm) and 16-pin VSON package with wettable flanks.
