Buck Switching Regulator IC Adjustable 1 Output 1000mA SOT-23-6 The LGS5145 is a step-down DC/DC regulator with internal switching, featuring SKIP control mode, which combines low quiescent current with high switching frequency to achieve high efficiency over a wide range of load currents. The SKIP mode uses a short “burst” cycle to switch the inductor current through the internal power MOSFETs, followed by a sleep cycle in which the power switch is turned off and the load current is supplied by the output capacitor. At light loads, the burst cycle is a fraction of the total cycle time, minimizing the average supply current and greatly improving efficiency at light loads. The LGS5145 has a wide input voltage range of 4.5V55V, minimizing the need for external surge suppression components.The LGS5145 features an integrated low resistance 0.6Ω high-side power MOSFET that provides at least 1A of output current capability with excellent load and line transient response.
