The EL7532IY-T7 is an integrated voltage regulator that belongs to the DC-DC switching regulator series produced by the company Elantec Semiconductor, Inc. This device is an easy-to-use, highly integrated, low cost switching regulator, designed to regulate output voltages from 0.8V to 5V. It has two outputs, so two separate output voltages can be regulated. In addition, the device can also operate as a constant current sink and/or a power limiter.

The EL7532IY-T7 is suited for applications in high-end consumer goods, such as digital cameras, audio players and PDAs. It is also suitable for many industrial, medical and communication systems, such as UPS systems, power supplies, battery chargers, battery management systems and telecommunication systems.

The EL7532IY-T7 operates according to the hysteretic control principle, which enables it to provide fast transient response and stable output voltage. The device also has a highly accurate voltage setting means that allows it to provide an output accuracy of ± 1%. The EL7532IY-T7 is designed with a variety of protective features to protect the device from overcurrent, overvoltage and thermal overload conditions.

The device\'s input voltage range is from 4.5V to 22V, and the output current can reach 1.5A (depending on the load characteristics) for reliable operation and maximum efficiency. The EL7532IY-T7 includes a shutoff pin that is activated when the voltage on the input supply is below a certain threshold, thus providing protection from undervoltage conditions. As for the output protection, the device provides an internal overvoltage protection that limits the output voltage to 5.5V.

The device has several features to help reduce the EMI emission. These include an integrated noise controller, an advanced compensation (including slope compensation) and a slew rate limitation. Lastly, the device has an integrated frequency jittering function that ensures noise immunity by frequency hopping on/off.

In summary, the EL7532IY-T7 is a highly integrated, low cost DC-DC switching regulator that provides variable output voltage and current regulation in a wide range of applications. It has an advanced compensation design and its switching frequency can be adjusted to minimize noise emission. Additionally, its voltage setting accuracy is ± 1%, and it has a variety of protective features such as overvoltage and thermal protection. This makes it suitable for applications where an accurate, efficient, robust and protected solution is required.
