DC-DC converters are widely used in a variety of applications ranging from industrial, commercial, medical and consumer applications. They are used to convert power from a single source or multiple sources to power a variety of electrical or electronic loads. PT6673L is a DC-DC converter chip provided by Protek Technology. It is a highly efficient, low power step-down DC-DC converter with integrated MOSFET. It provides improved power conversion efficiency in a small package while allowing for reduced system size and cost.

PT6673L is specifically designed for applications such as battery powered portable systems, distributed power architectures and have been extensively tested for automotive qualification. It features a low dropout voltage, low standby current and is capable of providing up to 3A output current. It also has a wide input voltage range and can operate over a wide temperature range. PT6673L is available in a 10-pin TSSOP package.

The PT6673L integrates a PWM controller, MOSFET, compensation circuit and feedback voltage reference into a single chip. It operates in either continuous or discontinuous mode, providing accurate output voltage regulation while minimizing the output ripple. The output voltage is factory programmed with a 1% accuracy over a wide output voltage range. The PWM controller provides a wide range of switching frequency and pulse width modulation for the output voltage regulation.

The PT6673L operates with a voltage input range of 6V to 36V and a switching frequency range of 300 kHz to 2 MHz. It provides a soft-start feature which helps eliminate large inrush current during startup. It also offers over temperature protection and over current protection. It allows for parallel operation with synchronization and can be controlled by an external enable pin. The operating junction temperature range is -40C to +125C.
