The LM4360x SIMPLE SWITCHER® family of wide voltage input regulators are easy to use synchronous step-down DC-DC converters capable of driving up to 3 A of load current from an input voltage ranging from 3.5 V to 36 V (42 V absolute maximum). The LM4360x family provides exceptional efficiency, output accuracy, and drop-out voltage in a very small solution size. An extended family is available in 0.5 A ,1 A, and 2 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, a 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 pin arrangement allows simple, optimum PCB layout. Protection features include thermal shutdown, VCC under-voltage lockout (UVLO), cycle-by-cycle current limit, and output short circuit protection. The LM4360x devices are available in the HTSSOP/PWP 16-lead package (5.1 x 6.6 x 1.2 mm). All the devices in this family, LM43600, LM43601, LM43602, LM43603, LM46000, LM46001, LM46002 are pin-to-pin compatible.
