DC DC Converters

The PT6671F is a type of DC DC converter, a device that "converts" electrical power from one direct current (DC) voltage form to another. It provides regulated DC output from an unregulated DC input, and also can protect any load it is driving from spikes, transients, and other voltage anomalies from the input source.

The PT6671F is specifically designed for electric vehicles, medical machines, remote-sensing data acquisition devices, instrumentation, and other applications requiring a clean, reliable, and cost-effective DC-to-DC conversion solution. It operates over an input voltage range of 18V to 48V and an output voltage range of 10V to 16V, making it suitable for a variety of applications.

The device consists of two identical buck converters operating in parallel, and provides up to 80A continuous output current and up to 400W of output power. This makes it capable of meeting the demands of a variety of applications, including ripple-free power for low power applications such as vehicle electronics.

The PT6671F operates as a fast-transient response synchronous buck converter, and features a 4-level synchronous rectifier architecture that results in higher efficiency and very low EMI. The device uses synchronous rectification to improve conversion efficiency and reduce power losses, and also has an integrated power-good signal that can be used to monitor and protect the load.

The device is also designed for thermal stability and reliability, and features an over-temperature protection that shuts down the converter when a critical temperature is exceeded. The PT6671F also integrates a low-noise high-performance voltage ripple filter, allowing for improved reliability and compliance with system level EMI limits.

The PT6671F is easy to use and configure, as it features programmable loop compensation, pre-bias startup, and can be used with both analog and digital control. The device also integrates a power-on reset circuit and a fault protection circuit to protect the load from input voltage excesses and system transients.

The PT6671F is a reliable and efficient DC-to-DC converter that provides high-performance, low-noise power conversion, and can be easily configured and monitored for both analog and digital operation. Its advanced protection features make it suitable for a wide range of applications, including electric vehicles, medical machines, data acquisition devices, instrumentation, and other applications requiring a clean, reliable, and cost-effective power conversion solution.
