TC1121COA713

TC1121COA713 is a DC-DC switching regulator designed to provide a regulated output voltage of up to 7.13V from an input voltage range of 3.3V to 22V. It is suitable for use in a wide range of industrial and consumer applications, such as communications equipment, point-of-sale terminals, gaming equipment, and portable electronics.

The TC1121COA713 is a monolithic switch-mode converter that integrates a 700mA, 3-phase MOSFET switching converter and a highly-accurate voltage regulator. It is designed to deliver high power efficiency, better than 90%, while minimizing conducted EMI and switching noise. It also features low spiky output ripple, low shutdown current, and low output voltage transition. In addition, the converter is protected against over-current, overtemperature, and under-voltage lockout.

At the heart of the TC1121COA713 is a 3-phase MOSFET driver, which controls the switching of the MOSFETs to convert the input voltage to the required output voltage. The 3-phase circuitry helps to improve efficiency by reducing switching losses, and further reduces conducted noise interference. A synchronous rectifier is also implemented in the circuit to ensure low power dissipation and improved overall efficiency.

The control circuitry of the TC1121COA713 utilizes a proprietary voltage-mode control technique to sense the output voltage and adjust the internal PWM control signal accordingly. This technique is more accurate and less sensitive to component variations than other types of control methods. The IC also has an internal compensation network that can be used to adjust the response of the regulator depending on the load and desired output voltage.

The TC1121COA713 also incorporates additional protection features such as over-current protection and soft-start. The over-current protection feature prevents excessive current flow through the device, while the soft-start feature prevents sudden, large in-rush currents when the device is powered on. Both of these features help to ensure the safe and reliable operation of the power system.

The TC1121COA713 is an ideal choice for applications requiring high-efficiency, low-noise and low-EMI power conversion. It is suitable for use in a wide range of industrial and consumer applications, such as communications equipment, point-of-sale terminals, gaming equipment, and portable electronics.
