SAN JOSE, Calif.--(BUSINESS WIRE)--Power management leader, Kinetic Technologies, is expanding its DC-DC Conversion portfolio with the introduction of KTB8400 OptiComp™ buck switching regulator. OptiComp is a unique architecture that combines the best attributes of the leading DC-DC control methods into a single design. It features fast transient response, ultra-low variation switching frequency across the load range, high efficiency and integrated compensation. KTB8400 is ideal for a variety of applications including CPU/GPU core, DSP, DDR memory, VIO, and sensor/analog power.
OptiComp’s highly controlled switching frequency avoids the common problems with popular architectures wherein light-load operation introduces unwanted EMI and increased output voltage ripple. KTB8400 is I2C programmable for output voltages in the 0.6V to 3.345V range. It features soft-start and DVS with multiple programmable ramp rates as well as programmable forced-PWM and auto-skip light load modes. Protection features include soft-start, over-current, short-circuit, under/over VIN, and thermal shutdown.
“OptiComp is a significant new addition to the DC-DC industry,” says Jan Nilsson, Chief Technical Officer at Kinetic Technologies. “It brings the best advantages of Voltage Mode, Current Mode and Constant On-Time architectures into a single high-performance IC, providing ultra-fast transient response, ultra-low variation in switching frequency without sacrificing small size, high efficiency and protection features. Up until now, it was commonplace in the industry where OEM designers were forced to prioritize transient response, fixed frequency or high efficiency, and then select the control method which provided the key specification while sacrificing the others. OptiComp is a game changer, using a patented PLL control scheme to combine all the strengths together in a single design.”
Key applications for the KTB8400 include Industrial Electronics, Sensors, Mobile Electronics, IoT Devices, Drones, Gaming Consoles and Accessories.
KTB8400 is available now. Visit Kinetic Technologies for more information.
