The LTC3633AEUFD-2#TRPBF is a step-down DC-DC switching regulator with a wide operating voltage range that can fit a variety of power supply solutions. It is a highly integrated, high performance product with features such as low noise and high efficiency, making it ideal for applications such as computer, server, and communications platforms.

Application Field

The LTC3633AEUFD-2#TRPBF operates over a wide input voltage range of 3.0V to 32V and has adjustable output voltage range of 0.8V to 16V. It can deliver output currents of up to 4A and supports a switching frequency of 250 kHz to 1.5 MHz, enabling systems with a wide variety of power requirements. The device is designed to simplify the design of advanced power solutions with its robust thermal performance, precise output voltage regulation, and adaptive synchronization feature that reduces audible noise.

It is suitable for high current applications, for example, server and communications platforms. It can also be used in other applications that require precise power, such as medical equipment, power supplies for consumer electronics, automotive systems, and portable devices.

Working Principle

The LTC3633AEUFD-2#TRPBF works in three steps. The first step is to convert the input voltage to a lower voltage by regulating the output voltage through a buck-type regulator. The second step is to adjust the frequency to the required level by controlling the oscillator frequency. Lastly, it controls the output voltage through a high-side adjustable current source and synchronizes the switching to the external clock.

The device has a high efficiency, low on-resistance power MOSFET integrated driver, allowing it to achieve up to 94% efficiency while operating over a wide input voltage range. The low quiescent current and ultra-low shutdown current of a typical 500 nA and 1uA respectively, retains features such as power good, enable and analog/PWM dimming control.

The device also offers integrated protection features such as precision current limit, overvoltage protection, undervoltage protection, thermal shutdown, and lockout. It has an anti-cross conduction feature that prevents the drives from entering the dead region when switching from heavy load to light load.

The integrated VCC monitor provides an undervoltage and overvoltage detection to ensure that the device is operating within its operational limits.

Conclusion

The LTC3633AEUFD-2#TRPBF is an ideal DC-DC switching regulator for applications that require precise power, efficiency, and high-current solutions. Its wide input voltage range makes it suitable for use in many different applications. It offers integrated protection features to ensure that it operates within its specified limits, and its adaptive synchronization feature reduces audible noise.
