PMIC - Gate Drivers

The 2EDN8524GXTMA1 is a special type of product within the PMIC - Gate Drivers category. It is developed jointly by two companies,Power Integration Semiconductor and IDT, and is targeted at the mobile and consumer markets.

The 2EDN8524GXTMA1 is a Dual-Mode buck-boost converter with an input voltage range of 2.2 - 4V and an output voltage of 1.6V. It operates at up to 600mA and features an integrated field-effect output MOSFET. It also incorporates a logic input control, which allows it to switch between the two operating modes to allow it to boost or buck the voltage as required.

The device also contains an undervoltage lock-out or UVLO, overvoltage protection or OVP, and overtemperature protection or OTP. These features protect both the device and the powered elements from damage in case of unexpected input or output events.

The 2EDN8524GXTMA1 has a wide range of applications, from powering low-power and ultra-low-power products such as memory and MCUs to powering portable consumer electronic products such as wearables and drones. This wide range makes it broadly applicable, as it can easily and safely produce the appropriate output voltage to power a wide variety of products.

The device has a number of advantages, of which the first is size. Its package is extremely small, making it suitable for applications that require a small amount of space. It is also very efficient, boasting a wide load-transient response and good thermal characteristics; meaning it is capable of supplying a large amount of current in a small form factor.

The 2EDN8524GXTMA1 also offers lower component count and noise reduction due to the wide-range of output voltages it offers. Additionally, overvoltage, undervoltage, and overtemperature protection allows for greater safety and reliability.

Working Principle

The 2EDN8524GXTMA1 is a Dual-Mode buck-boost converter that works by shifting the input voltage to a regulated output voltage. It does this by using a combination of power switching, inductors, and capacitors to transform the input voltage. The converter is operated in buck or boost mode, depending on the input and output voltages.

In Buck Mode, the inductor stores energy and acts as a low-pass filter, allowing only DC signals to pass and blocking AC noise. The inductor is then connected to the output stage, which is modulated by the output switch and compensator, resulting in the output voltage being regulated.

In Boost Mode, the output stage switches on and the capacitor stores energy, allowing the output voltage to be increased. In this mode, the inductor blocks AC noise, while the output switch and compensator regulate the output voltage.

The 2EDN8524GXTMA1 also incorporates an integrated field-effect output MOSFET which allows for lower power dissipation as well as higher efficiency. In addition to this, the device has integrated protection features such as OVP, UVLO, and OTP.

Conclusion

In conclusion, the 2EDN8524GXTMA1 is an ideal product for a wide range of applications, from low-power and ultra low-power products to consumer electronic products. It has a wide range of output voltage options and is highly efficient, while also offering protection features to ensure a safe and reliable operation. It is thus an ideal choice for a wide range of applications.
