EN5322QI Power Supplies - Board Mount

DC-DC converters are vital components in the supply of power to heavy-duty electrical and electronic systems. The EN5322QI is an especially efficient and reliable power converter. It provides an ideal high-efficiency means for providing intermediate voltage rails to multiple digital and analog loads.

The EN5322QI implements fixed-frequency power conversion with a wide range of input voltage, typically 14.4V to 35.0V, which makes it suitable for different types of applications. It also has an external clocking feature ranging from 125kHz – 1MHz that is suitable for many wireless communications applications. The power conversion process that the device utilizes is known as PFM control. The EN5322QI also implements a patented architecture to allow efficient power conversion under no-load, low-load and high-load conditions. In addition, the EN5322QI features an integrated two-phase inductive boost converter, providing higher power density

In terms of working principle, the EN5322QI utilizes Pulse-Frequency Modulation (PFM) control to reach peak efficiency throughout a wide range of load conditions. PFM is a control technique in which the output voltage is regulated by modulating the duty cycle of the converter to maintain a relatively consistent frequency. This technique requires fewer components than other control techniques such as Pulse-Width Modulation (PWM). As a result, power density and efficiency are maximized.

The EN5322QI is capable of providing output power up to 5W. The device also features multiple protection circuits, such as over-current protection, short-circuit protection and thermal shutdown, that provide an extra layer of protection against faults and maintain long term reliability of the converter.

The EN5322QI DC-DC converter is an ideal solution for providing intermediate voltage rails to multiple digital and analog loads. It provides high efficiency operation and is protected against several fault conditions. With its wide range of input voltage and external clocking option, the EN5322QI makes a compelling choice for a variety of different applications.
