E-L6925D013TR Application Field and Working Principle

The E-L6925D013TR is a highly integrated DC DC buck switching regulator that provides the high conversion efficiency, wide input voltage range, low power dissipation, and fast transient response necessary in a variety of modern power management applications. This device is designed for applications that require voltage regulation of 1.5V/3.3V/5V/9V/12V, and is available in a wide range of package styles.

Application Field

The E-L6925D013TR is suitable for a variety of applications, including notebook computers, automotive systems, digital cameras and camcorders, communications systems and video game systems, where a reliable and high-performance voltage regulation solution is required. This device operates over the input voltage range of 2.4V to 5.5V, allowing it to be used with a variety of power sources, including lead-acid and nickel-metal hydride batteries, as well as from USB sources.

The E-L6925D013TR is specifically designed for low-power applications such as electronic point-of-sale terminals and wearables where its low power consumption, high efficiency, and small size enable the design of small, light, and efficient systems.

Working Principle

The E-L6925D013TR operates by using the Bucks-Type converter technique. This technique works by the circuit first charging and discharging an inductor with a high voltage, which then passes the energy on to a capacitor. This causes the voltage regulators output to be held steadily at the desired voltage level.

The controller has three operating modes including burst mode, pulse skipping and normal operation. In burst mode, the controller produces a series of pulses when an input voltage is applied, gradually increasing the pulse width until the desired output voltage is achieved. In pulse skipping mode, the controller generates no pulse when an input voltage is applied, provided the input voltage is greater than the output voltage, the controller switch is OFF and only regeneration occurs. If the input voltage is lower than the output voltage, the controller switch is ON and normal operation occurs.

The main advantage of the E-L6925D013TR is that it provides high conversion efficiency with minimum power dissipation and fast transient response. The device has two power save modes to reduce power consumption at light loads and to improve efficiency at low input voltages, allowing for greater system reliability and longer battery life.

Conclusion

The E-L6925D013TR is a highly integrated DC DC buck switching regulator that provides an efficient and reliable voltage regulation solution for modern power management applications. The device is suitable for applications that require voltage regulation of 1.5V/3.3V/5V/9V/12V, and is available in a wide range of package styles. The E-L6925D013TR operates by using the Bucks-Type converter technique, providing high conversion efficiency, low power dissipation, and fast transient response.
