EL7534IYZ-T13

The EL7534IYZ-T13 is a versatile, high speed DC/DC switch-mode regulator designed for applications that require highly efficient power conversion across a wide range of input and output voltages. The device is capable of operating from a wide range of input voltages ranging from 1.5V to 14V, and is capable of providing an output current up to 2A. The device also features a low quiescent current and uses minimal external components, making it suitable for applications requiring high efficiency and reliable operation.

The EL7534IYZ-T13 features a flexible power switching topology, with options for pulse-width modulation (PWM), pulse frequency modulation (PFM), and hysteretic mode control. The PWM and PFM control modes both support step-down (buck) and step-up (boost) configurations. In addition to high conversion efficiency, the device also provides excellent transient response, good line and load regulation, over-current protection, over-temperature protection, and dual synchronous outputs.

The device\'s integrated power MOSFETs provide high-efficiency switching up to 1.2MHz, which enables the design of very small external components. The EL7534IYZ-T13 also provides excellent thermal performance, allowing for operation in compact packages. The device can be used in a wide range of applications including communications, automotive, industrial, computing, and consumer electronics.

The EL7534IYZ-T13 works by converting the input voltage to an intermediate voltage and then converting the intermediate voltage to the desired output voltage. The intermediate voltage is generated by a voltage regulator, which is powered by the input voltage. The voltage regulator controls the voltage at the output of the regulator, and the output voltage is then regulated by the DC/DC switching regulator. The switching regulator operates by switching the input voltage on and off in response to the output voltage, thus controlling the output voltage.

In PWM mode, the output voltage is controlled by controlling the duty cycle of the output voltage to correspond to the desired output voltage. In PFM mode, the output voltage is controlled by adjusting the switching frequency based on the load conditions. The hysteretic mode control works by switching the output voltage on and off in order to maintain a defined output voltage. By varying the voltage set-point, the output voltage can be regulated within a certain range.

The EL7534IYZ-T13 provides excellent performance in a wide range of applications, such as voltage regulation, battery charging, current limiting, LED driving, and multi-output voltage control. It is well suited for use in portable electronics, automotive, and other applications requiring high efficiency and reliable operation. It is available in a variety of package sizes, including small QFN and SOT packages.
