DC-DC Converters

DC-DC converters are devices which convert electricity from one DC voltage to another with the aid of an external power supply. These converters provide the flexibility to operate from a wide range of input voltages, and can also serve as DC power converters to provide power to sensitive circuitry which requires a clean and consistent DC voltage. The PT6605F is a DC-DC converter that offers a high efficiency solution for regulating the output voltage of supplies with a wide range of input voltages.The PT6605F is a step-up and step-down DC-DC converter with a built-in switching FET. This device is designed for applications where the input voltage can vary between 4.5V and 24V, and the output voltage needs to be between 5V-30V. It is capable of outputting up to 8A and achieves efficiencies as high as 97%. The device also includes a class-leading quiescent current of 10μA which helps save power when the output load is low.The PT6605F utilizes a unique buck-boost design where it provides a boost voltage on its output whenever the input voltage is below the output voltage. This unique design eliminates the need for an external diode and reduces the total solution size. Additionally, the PT6605F incorporates an internal 40V clamp which will protect the device from surges, making it well-suited for automotive applications.When using a regular buck-boost converter, the output voltage must be configured to the expected input voltage, otherwise the output may oscillate or the output voltage may not be accurate. The PT6605F simplifies this process by incorporating an active voltage dimming feature which can sense the input voltage and adjust the output voltage accordingly.The PT6605F uses a synchronous rectification topology to provide even higher efficiency and low noise during switching transitions. It also incorporates a proprietary cycle-by-cycle current limit protection circuit which guarantees a stable operation even under extreme load conditions. The output voltage can be adjusted over a wide range via an external resistor, allowing for the flexibility to adjust the output voltage as needed.In addition to its power saving features, the PT6605F also includes a wide range of advanced protection features. These include: feedback-overvoltage protection, current limit protection, thermal shutdown with hysteresis, over-temperature protection, short-circuit protection, and reverse battery protection.The PT6605F is an ideal solution for applications which require efficient conversion from one DC voltage to another. With its wide input voltage range, high output current capability, and comprehensive protection features, the PT6605F is an ideal choice for power-sensitive and safety-critical industrial, automotive, and consumer applications.
