EL7532IYZ-T7 is a DC-to-DC switching regulator integrated circuit that belongs to the family of PMIC (Power Management Integrated Circuits). As part of the "Voltage Regulators and Switching Regulators" subgroup, DC-to-DC switching regulators are used to convert an input DC voltage to a lower output DC voltage. This is realized by using an energy accumulating element (integrated inductor, for instance) that stores energy and delivers it to the output in the form of current pulses, thus achieving voltage conversion. The EL7532IYZ-T7 is an ideal solution for applications such as battery-powered systems (using a single Li-ion/LiFePO4 cell) or any low-power source requiring step-down voltage conversion to as low as 0.6V.The EL7532IYZ-T7 uses synchronous rectification to achieve a very high efficiency while regulating the output voltage with a high accuracy and low output voltage noise. It is one of the most optimized and efficient parts in terms of power management, offering a high-performance switching regulator with low power loss and compact size.The EL7532IYZ-T7 provides a very accurate regulation with a minimum output voltage ripple, switching noise, and a fast transient response without the need for external compensation components. It must be enabled by activating the EN pin, then the output voltage is controlled by a defined input voltage applied to the VIN pin. The output voltage is adjustable with a voltage divider, while the output current is limited with a current-sense resistor connected to the ISENSE pin, making it suitable for a wide range of current regulation needs. Furthermore, the thermal protection control, soft-start function and UVLO (Under-Voltage Lock-Out) provide the necessary safety features and make the EL7532IYZ-T7 a reliable and robust partner for high efficiency applications.When the EN pin is activated, the switching MOSFET is enabled and the current begins running through the integrated inductor, storing energy and delivering it when the switch is off. The output voltage is regulated by an internal voltage feedback loop and an external voltage divider. The voltage divider utilizes a ratio dependent on the output voltage desired. In case of excess load or current, the current-sense circuitry will shut down the device, protecting it from excessive power dissipation.The EL7532IYZ-T7 is the perfect solution for applications requiring efficient and accurate step-down voltage conversion with little power dissipation and high output-voltage accuracy. It offers the best balance between size and performance, ideal for applying in battery-powered systems, low-power embedded designs, as well as portable and consumer electronic products.
