The TC1303A-ZI0EUNTR is a linear and switching regulator integrated circuit (IC) used in multiple devices. It is a low-voltage, low-quiescent current regulator that provides a high performance, low voltage regulated output, with both linear and switch-mode operation. Used in critical applications, the TC1303A-ZI0EUNTR is critical for use in battery-powered, high-efficiency systems. The internal control loop ensures small time-dependent operating current for timed functions, resulting in low average power consumption.
Working Principle: The TC1303A-ZI0EUNTR IC uses Voltage Discontinuous Mode (VDM) control to achieve both the linear and switching control. VDM operates by turning the linear regulator’s output transistor OFF when required, and then turning it ON to reach the desired output voltage. It has two different feedback control loops: one to provide differential gain and the other critical gain control. The differential feedback loop is used to set up the loading of the output stage and the linear sensing amplifier for current limiting. The critical gain control loop is used for frequency compensation and reduces the output voltage ripple.
Application: The TC1303A-ZI0EUNTR is used for a wide range of applications. These include powering LCD displays, Interface Control Boards, Audio Amplifiers, Data Converters, Voltage Regulators, Gate Drivers, Motor Drivers, DC/DC Converters, Audio Power Amplifiers, Switching Regulated Outputs, Battery Chargers and more. In addition, the components used in the device are designed to reduce the Radiated Emissions to ensure the product meets EMC (electromagnetic compatibility) compliance.
The TC1303A-ZI0EUNTR also includes protection features like Over-Current Protection, Over-Voltage Protection, Short-Circuit Protection, Over-Temperature Protection and Power Good (PGOOD) output. The Integrated Overcurrent Protection eliminates the need for external current-sensing circuitry. Furthermore, the component contains a novel voltage multiplier structure that enables higher output voltages and high efficiency.
The TC1303A-ZI0EUNTR offers a wide range of advantages in terms of size, cost and efficiency. Its state-of-the-art design delivers a maximum output of either 0.6V/0.9V/1.2Voutput (depending on the model selected) with a high efficiency of up to 95%. In addition, its low-voltage output allows it to be used for a variety of applications. As a result, the TC1303A-ZI0EUNTR is a reliable, accurate and low-cost way to power a variety of portable devices.
