LM436xx/LM460xx SIMPLE SWITCHER® Regulators

TI's 3.5-60 V, 0.5-2 A, easy-to-use synchronous step-down voltage converters

Image of Texas Instruments' LM436xx/LM460xx SIMPLE SWITCHER® RegulatorsTexas Instruments' LM436xx/LM460xx SIMPLE SWITCHER® regulators are easy-to-use synchronous step-down DC-DC converters capable of driving up to 2 A of load current from an input voltage ranging from 3.5 to 60 V. These devices provides exceptional efficiency, output accuracy and drop-out voltage in a very small solution size. An extended family is available in 0.5 A and 1 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 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.
