The RT8101GSP is a member of Richtek\'s series of advanced step-down converters. It is a monolithic Power Management Integrated Circuit (PMIC) with a voltage regulator specifically designed for DC-DC Switching Controllers. It provides up to 2.1A of output current in an ultra-small package. With its high efficiency, low output ripple, and excellent line and load transient response, the RT8101GSP is ideal for portable applications such as notebook/tablet/smartphone power supplies as well.

The RT8101GSP is designed to provide an accurate load regulation and excellent load transient performance under a wide variety of load and line conditions. Its operating frequency is adjustable up to 2MHz, allowing for greater flexibility when selecting external components. The integrated soft-start and programmable output slew rate provides the designer with more advanced system control options. The device also provides integrated current limiting and thermal protection features, making it suitable for any given application.

The RT8101GSP provides flexible control options, allowing the user to choose between Voltage Mode (VM) and Pulse-Width Modulation (PWM) control. In Voltage Mode Control, the output voltage is maintained at a constant level. The RT8101GSP features a wide range of voltage loop compensation, ensuring an accurate and stable control of output voltage. In Pulse-Width Modulation Control, the device adjusts the on-time of the output switch, modulating it to maintain a constant output voltage with lower output ripples.

The RT8101GSP\'s advanced current-mode returns excellent line and load transient response. Its proprietary MOSFET gate driver is designed to provide enhanced gate drive with fast edge speeds and minimal gate charge. The RT8101GSP also provides integrated gate-driving capability for synchronous rectification, allowing for higher power conversion efficiency.

The RT8101GSP also features a wide range of protection features. It is protected against over-voltage, under-voltage, and over-current conditions. The device also features a selectable current-limit delay to allow maximum flexibility when configuring the device. The RT8101GSP also features short-circuit protection. Additionally, the device provides a power-on-reset feature, which ensures proper system start-up under extreme conditions.

Due to its advanced features and protection features, the RT8101GSP is ideal for a wide range of DC-DC switching controller applications, such as notebook/tablet/smartphone power supplies and other low-value power solutions. With its integrated soft-start and programmable slew rate, it is perfect for applications that require optimal system control. Thanks to its integrated gate driver and current limiting and thermal protection, the RT8101GSP provides an easy, intuitive, reliable and cost-effective solution for applications that require efficient power conversion.
