IQE48040A033V001R

The IQE48040A033V001R is a DC DC converter widely used in the design of industrial, automotive, and consumer electronic products. It is an adjustable buck regulator designed to provide an efficient and reliable output voltage source for applications that require a wide input voltage range, high efficiency, and excellent transient response. It features an adjustable output voltage employed with an external resistor voltage divider network set in order to provide accurate voltage level control even under extreme temperature and load conditions. It can also be set to operate in either constant voltage or current mode depending on the application.

The IQE48040A033V001R is typically used in applications that require a wide input voltage range (4.5V to 18V), high efficiency, and long-term reliability. It is commonly seen in mobile applications where a wide operating temperature range and extended battery life are both important factors. It is also used in green energy applications such as solar powering and wind power where voltages are continually variable and the application must be designed to handle fluctuations in power output.

The IQE48040A033V001R is capable of delivering up to 25A continuous at 3.3V from an input voltage range between 4.5V and 18V. It features an adjustable output voltage employed with an external resistor voltage divider network set in order to provide accurate voltage level control even under extreme temperature and load conditions. It also provides excellent transient response, making it suitable for automotive applications.

The IQE48040A033V001R includes an integrated under-voltage lockout, over-voltage protection, over-current protection, and thermal shutdown protection. The built-in current limit provides an additional safety feature. The IQE48040A033V001R is also designed to be used with an external MOSFET or P-Channel MOSFET to provide additional power handling capabilities and improved efficiency.

The working principle of the IQE48040A033V001R is centered around its control circuitry, consisting of an internal PWM controller, one or two error amplifiers, and an enable logic system. The internal PWM controller is responsible for regulating the output current to a specific level. The error amplifier allows the converter to respond quickly to changes in output voltage or load current. The enable logic system serves as an on/off switch to the converter, allowing it to save energy when not in use.

In summary, the IQE48040A033V001R is a high-performance DC DC converter suitable for a variety of industrial, automotive, and consumer applications. It is capable of delivering up to 25A of continuous current at 3.3V from an input voltage range of 4.5V to 18V. Its adjustable output voltage feature, wide operating temperature range, and built-in protection features make it an ideal choice for many demanding applications.
