LM4360x/LM4360x-Q1 SIMPLE SWITCHER® Regulators

Texas InstrumentsLM4360x/LM4360x-Q1 SIMPLE SWITCHER® Regulators are an easy to use synchronous step-down DC-DC converter capable of driving up to 3A of load current from an input voltage ranging from 3.5V to 36V (42V transient). The LM4360x/LM4360x-Q1 provides exceptional efficiency, output accuracy, and drop-out voltage in a very small solution size. 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 pin arrangement allows simple optimum PCB layout. Protection features include thermal shutdown, VCC under-voltage lockout, cycle-by-cycle current limit, and output short circuit protection. The Texas Instruments LM4360x-Q1 devices are AEC-Q100 qualified for automotive applications.
