The E-L4960 is an integrated circuit that’s used in a variety of applications that require a reliable and efficient way to regulate voltages from one source to another. It’s a part of a comprehensive voltage regulator and DC-DC switching regulator system. This application notes will provide an overview on the general purpose and the specialized uses for this particular type of IC, as well as the working principles behind it.

Application Field

The E-L4960 is a dual-output, adjustable, Pulse Width Modulated (PWM) voltage regulator. It is most commonly used in applications requiring high voltage and current capability, such as in powering motors, LEDs, and other major devices. It is also used in power backlighting and power management systems, providing a safe and efficient way to control the power to these devices. It features an adjustable output voltage range and can provide currents of up to 10A at 10V, making it a very capable IC for powering larger devices and applications that require higher current output.

In addition to its uses in powering major devices, the E-L4960 is also widely used in battery-operated equipment. The integrated MCU and charging control logic ensures the IC can be used in a wide variety of battery-operated applications such as handheld radios, portable medical instruments, and other portable electronics. With its integrated high-voltage start-up and adjustable voltage selection, the E-L4960 is designed to be highly suitable for battery-operated applications, allowing the user to select the optimal voltage output for the device.

Working Principle

The E-L4960 is an adjustable, Pulse Width Modulated (PWM) voltage regulator. It is used in many applications with power backlighting and power management needs, because it can regulate the power and electrical signals that are sent from various sources, ensuring the circuitry operates efficiently. PWM is an effective way to regulate the voltage for LEDs and LCDs that require a certain voltage level. It uses periodic pulses, with a variable duty cycle, to regulate the power to the connected device.

The E-L4960 works by the cycling of a shifting process that occurs between the two outputs—a high side “L” and a low side “H”. When the “L” output is low, the voltage fed into the device is less than the desired amount, which keeps the device powered on but not at an optimal level. When the “H” output is high, the voltage is more than the desired amount, and the device is preloaded with a higher level of power than it needs. By cycling between these two states, the E-L4960 is able to regulate the amount of power that is sent to the device, ensuring that it is the optimal level.

The E-L4960 also features a high voltage start-up, which ensures that devices can be safely and efficiently powered in multiple applications. This high voltage start-up allows for the device to be safely powered in an application requiring higher than 12V, such as most portable devices. The adjustable voltage selection also helps to ensure the device is being powered to the optimal level for its application.

Conclusion

In conclusion, the E-L4960 IC is a versatile and highly dependable IC that’s used in a wide variety of applications, including powering LEDs and LCDs, motors, and battery-operated equipment. It’s designed to provide a safe and efficient way to regulate voltage from one source to another, as well as providing integrated high-voltage start-up and adjustable voltage selection. Its use of Pulse Width Modulated power regulation makes it a highly reliable and dependable means of delivering power to devices, ensuring they are powered to the ideal level. With its wide range of uses and reliable operation, the E-L4960 is a great addition to any system requiring reliable power regulation.
