The RT8060A is a current mode, high efficiency PWM step-down DC/DC converter that can support a wide input voltage range from 2.7V to 5.5V, while delivering up to 1A output current. The current mode operation provides fast transient response and eases loop stabilization. A 1.5MHz frequency operation allows the use of a smaller inductor to meet the space and height limitations handheld applications. The RT8060A is available in a SOT-23-5 package.
