UC2573DG4

UC2573DG4 is a low-cost, switched-mode voltage regulator, designed for use in a wide range of DC-DC controllers. It is based on the company\'s proven CMOS process and offers a cost-effective solution to voltage regulation needs. The UC2573DG4 is a dual-channel device designed to control the output voltage of any DC-DC converter. It can be used in applications such as high-current DC-to-DC converters, DC-to-AC inverters, and low-voltage DC-to-DC converters.

The UC2573DG4 operates in two modes: fixed-frequency operation and voltage-mode control. In fixed-frequency operation, the device operates at a fixed frequency, typically in the 50-500 kHz range. The output voltage of the regulator is determined by a resistor-divider network that sets the voltage reference. The voltage reference is compared to the input voltage, and the output voltage is adjusted accordingly.

In voltage-mode control, the device operates at a variable frequency, typically in the 1-100 kHz range. The voltage reference is set by the user, and the output voltage is adjusted to maintain the set voltage. In both modes, the device also allows for additional control of the output voltage via an external sense pin or by using an external voltage reference.

The primary application of the UC2573DG4 is in DC-DC controllers that require precise voltage regulation. It can be used in a wide range of applications, including standby power supplies, automotive engine control systems, and notebook computers. The device is also suitable for use in applications such as voltage converters, high-precision motor control, and ultra-low-voltage DC-DC converters.

The UC2573DG4 is a versatile, low-cost voltage regulator that offers excellent performance and flexibility. It is well suited for use in a wide range of DC-DC controllers that require precise voltage regulation. With its low cost, it is particularly suitable for cost-sensitive applications requiring a reliable regulator.
