PTH08080WAZ

DC DC Converters

A DC-DC converter is a device that mimics a direct current (DC) power supply, enabling the conversion of DC power from one system or circuit to another. DC-DC converters provide a regulated voltage output and can be used to increase, reduce or isolate a voltage from the input voltage. They are often used in applications where the input voltage or the output voltage needs to be increased, decreased or isolated from the input. Some of the more common applications for DC-DC converters include regulating LED lighting and battery charging.

The PTH08080WAZ is a high-performance DC-DC converter designed to provide reliable industry-standard power conversion. It features a wide 4:1 input voltage range (6-24V) and delivers an adjustable output voltage (1.8V-28V) with high efficiency (typical efficiency up to 95%) and tight regulation (typically 0.2%) over a wide load range (1.73A max). It has a low standby current, and can be employed in harsh environments and in applications requiring a high degree of diagnostics.

The PTH08080WAZ features a variety of protection and control functions, including over-voltage protection, excessive power limiting, and low quiescent current shut-down. It is protected against over-current, short-circuit, and overtemperature conditions, helping to prevent component damage due to these occurrences. The converter also provides current monitoring, which gives the user the ability to monitor the delivery of the output current in real-time.

At its core, the PTH08080WAZ is a highly efficient insulated gate bipolar transistor (IGBT)-based DC-DC converter, allowing for highly regulated power conversion over a wide range of input and/or output voltages. By pairing a series of IGBTs and diodes, it creates a level-shifted three-winding power topology that is often used in medium to high voltage SMPS topologies. Using this design, the PTH08080WAZ is able to provide the user with high voltage conversion and isolation between input and output, and low input current ripple.

The PTH08080WAZ also features an automatic switches-off voltage protection, which shuts down the converter when the input voltage falls below 6V for extended periods. This protects the converter from damage caused by a low input voltage and helps ensure reliable operation in a wide variety of applications. Additionally, this feature also helps prevent the converter from producing excessively high output voltage when exposed to low input voltage conditions.

The PTH08080WAZ can be used in a variety of applications, from basic regulated DC-DC conversion to power conditioning for telecommunications systems. Its wide input and output voltage range make it suitable for a variety of tasks, and its high efficiency and reliable operation provide reliable performance in challenging environments. Its current monitoring feature also allows users to closely monitor the performance of their system, enabling them to take corrective actions when necessary.
