TPS59610RHBR

The TPS59610RHBR from Texas Instruments is a high-performance single-phase synchronous buck controller featuring the D-CAP+ control mode. It is specifically designed for embedded computing applications, targeting CPU and GPU power delivery that adheres to the IMVP6+ specification. This controller supports a wide input voltage range from 3V to 28V, with an output voltage adjustable from 0.3V to 1.5V. It can handle a maximum output current of 60A and boasts a typical quiescent current of 1.8mA. The device ensures high accuracy with ±8mV V CORE accuracy over line, load, and temperature variations. It operates within a temperature range of -40°C to 105°C and offers selectable switching frequencies of 200, 300, 400, or 500 kHz. The TPS59610RHBR is available in a 32-pin, 5mm x 5mm QFN PowerPAD package, minimizing external component count and board space.

Key features include adjustable current limit, enable functionality, light load efficiency optimization, power good indication, SVID support, and UVLO protection. The controller also incorporates patented output overshoot reduction (OSR) to minimize output capacitance requirements and accurate, adjustable voltage positioning. Its fast FET driver with an integrated boost diode and an integrated OVP that can be disabled further enhance its design flexibility. The dual-mode DAC supports both 5-bit and 7-bit VIDs, ensuring compatibility with various CPU and GPU power management protocols. This makes the TPS59610RHBR an excellent choice for demanding embedded computing power solutions.
