The LT1936EMS8E#PBF is a 500kHz Step-down Switching Regulator with an internal 1.9A power switch. The wide input range of 3.6 to 36V makes it suitable for regulating power from a wide variety of sources, including unregulated wall transformers, 24V industrial supplies and automotive batteries. Its high operating frequency allows the use of tiny, low cost inductors and ceramic capacitors, resulting in low, predictable output ripple. Cycle-by-cycle current limit, frequency fold back and thermal shutdown provide protection against shorted outputs and soft-start eliminates input current surge during start-up. Transient response can be optimized by using external compensation components or board space can be minimized by using internal compensation. The low current (<2μA) shutdown mode enables easy power management in battery-powered systems.
