Texas Instruments TPS59603-Q1 Synchronous Buck FET Drivers

Texas Instruments TPS59603-Q1 Synchronous Buck FET Drivers are optimized for high-frequency CPU VCORE applications. Advanced features such as reduced dead-time drive and auto-zero crossing are used to optimize efficiency over the entire load range. The SKIP pin provides the option of CCM operation to support the controlled management of the output voltage. Also, the Texas Instruments TPS59603-Q1 supports two low-power modes. With the PWM input in tri-state, the quiescent current is reduced to 130µA, with an immediate response. When SKIP is held at tri-state, the current is reduced to 8µA (typically 20µs is required to resume switching). Paired with the appropriate TI controller, the drivers deliver an exceptionally high-performance power supply system. The TPS59603-Q1 device is packaged in a space-saving, thermally-enhanced 8-pin, 2mm x 2mm wettable flanks WSON package and operates from –40°C to 125°C.
