The SC2434SWTRT is a tri-phase, current mode DC/DC controller designed for high-performance microprocessor applications. It operates with Semtech smart synchronous drivers, allowing for efficient power management. The controller features input current sensing for precise phase-to-phase current matching using a single sense resistor, which reduces power loss and complexity compared to traditional output current sensing methods. It supports selectable two or three-phase operation, enhancing transient response and minimizing input/output ripple. The device includes programmable DAC step size and range, accommodating emerging VID ranges, and implements active droop to optimize output capacitor requirements during load transients. The SC2434SWTRT is suitable for applications such as Intel Pentium-4 microprocessors and high-performance desktop systems. The controller is housed in a TSSOP-20 package, making it compact for integration into various designs.
