The Micrel MIC2177 is a 200kHz synchronous buck (step-down) switching regulator designed for high-efficiency, battery-powered applications. It operates from a 4.5V to 16.5V input and can supply up to 2.5A output current. The regulator can operate in PWM or skip mode, depending on the output conditions, to achieve high efficiency over a wide output current range. It features a shutdown mode that reduces quiescent current to less than 5µA. The MIC2177 uses current-mode control with internal current sensing, providing superior line regulation and easy compensation of the control loop. It is protected against pulse-by-pulse current limiting and thermal shutdown. The output is turned off when the input voltage is less than 4.5V. The MIC2177 is packaged in a 20-lead wide power SO package with an operating temperature range of –40°C to +85°C.
