DC-DC converters are electronic circuits that convert power from one DC voltage source to another, or from one DC voltage to an AC voltage output. The PT6625B is a DC-DC converter designed to provide a regulated output voltage from an input voltage that is at least 1.2V higher than the output voltage. This converter is designed to provide an output current of up to 1 amp and features over-voltage and over-current protection, as well as temperature protection and short-circuit protection.

The PT6625B DC-DC converter is a powerful and cost-effective solution for supplying a regulated output voltage from sources such as batteries, solar panels or other DC sources. It is particularly suitable for powering autonomous low-power devices, such as wearables, embedded or other electronic systems.

Features and Benefits

The PT6625B is designed with a wide range of features and benefits that make it a great choice for applications requiring a reliable and efficient DC-DC converter. The features and benefits provided by the PT6625B converter include:

• Low ripple and noise
• Wide input range (1.2V to 9V)
• Output voltage adjustable from 0.8V to 8V
• Protection circuit with over-current and over-voltage protection, temperature protection, and short-circuit protection
• High efficiency (up to 91%)
• Low quiescent current
• Small footprint (10mm x 10mm)

Application Field and Working Principle

The PT6625B DC-DC converter can be used in a variety of applications. It is particularly suitable for low-power devices such as wearables, embedded, and other electronic systems, owing to its small footprint and built-in protection circuits. The PT6625B can also be used in applications such as motor control, LED lighting, solar energy charging, medical devices, automotive applications, and industrial automation monitors.

The PT6625B DC-DC converter uses an emulated current mode control technique. This technique works by detecting the output voltage feedback and using this information to control the Pulse Width Modulation (PWM) transfer interval accordingly. This provides an accurate voltage output and fast transient response, while the emulated current mode control also assists with the stable switching operation characteristic of the converter. The PT6625B converter also utilizes a synchronous rectification technique, which helps to reduce losses down to a minimum and increase the overall converter efficiency.

In addition to the features mentioned, the PT6625B DC-DC converter also offers a wide range of customization and options. The output voltage can be adjusted from 0.8V to 8V, and the maximum output current can be set to 1A. The converter also offers a range of protection features, including over-current protection, over-voltage protection, temperature protection, and short-circuit protection.

The PT6625B DC-DC converter is an excellent choice for applications requiring a reliable and efficient DC-DC converter. Its wide range of features and benefits make it an ideal solution for low-power autonomous devices, as well as other applications that require a reliable and cost-effective power supply.
