RT8060
1.5MHz, 1A High Efficiency Step-Down Converter
General Description
The RT8060 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 RT8060 is available in a SOT-23-5 package.
