PT6655M

DC-DC Converters are often used in power systems to provide a desired power output from a given input power source. PT6655M is an integrated DC-DC converter specifically designed to provide indoor and outdoor applications requiring step-up or step-down voltage conversion. It features integrated power MOSFETs and maximum 3A continuous short-circuit current. It features an operating frequency up to 2MHz, so can be used in a wide range of applications.

The modern PT6655M provides highly efficient power conversion functions and is suitable for input ranges from 4.5 V to 60 V. It also features an integrated overcurrent, overtemperature, and overvoltage protection making it suitable for many applications such as:

• Industrial applications for powering LED lighting and sensors, for electronic assembly tools, and for motor control.
• Medical electronics for powering digital imaging and diagnostic tools.
• Automotive electronics for powering sensors in cars and trucks.
• Aerospace electronics for powering navigation and communications systems.

The PT6655M offers several key advantages for its customers when compared to other DC-DC converters. It is compact, at just 11 mm x 9.7 mm, making it easy to install in tight spaces. Additionally, it features onboard current-mode PWM regulation and input and output voltage and current limiting, which makes it ideal for high power applications. It also features a high operating frequency of up to 2 MHz, which ensures fast regulation and fast transient response times.

The PT6655M is based upon a synchronous rectification power conversion topology which uses N-channel MOSFETs to regulate input and output voltage. It includes two integrated N-channel power MOSFETs, one on the input side and one on the output side, to provide a low voltage drop solution. The N-channel MOSFETs are coupled to optimized control logic to coordinate the switching actions and to provide a suitable compensation network for current mode regulation. This synchronous rectification topology provides a high efficiency conversion solution in a reduced-size package.

The PT6655M features integrated short-circuit protection, thermal shutdown, overvoltage protection, and a programmable soft-start to reduce inrush currents. Additionally, it also features an integrated power-good signal for easy monitoring of the output voltage. It also has an adjustable switching frequency that can be set between 500 kHz and 2 MHz to optimize performance.

In summary, PT6655M DC-DC converter is ideal for a wide range of applications, such as industrial and automotive electronics, and medical and aerospace electronics, where space is a concern. It is a highly integrated, compact power solution offering exceptional performance, with integrated overcurrent, overtemperature, and overvoltage protection.
