It can provide up to 500mA output current, with a high efficiency of up to 89%. It also supports adjustable output voltage settings, allowing users to easily modify their settings based on their application requirement.

The TC1303B-DF0EMFTR features a wide range of features including output on-off control to control the main power, output voltage sequencing and sequencing control, power-down control, and fault protection. It also offers a wide range of package options, making it suitable for a variety of applications.

Output

The TC1303B-DF0EMFTR consists of two separate linear regulators (LDO) and a high-efficiency switching buck regulator. It supports two separate output voltages from 0.8V to 8.0V. The first LDO has an adjustable output voltage that can range from 0.8V to 8.0V and can provide up to 240mA of output current. The second LDO has a fixed output voltage of 3.3V with a max output current of 160mA. The buck converter provides up to 500mA of output current, with a wide input battery range of 2.5V to 5.5V, and a switching frequency of 1.2MHz.

The TC1303B-DF0EMFTR offers many different protection features such as over current, over voltage, and thermal protection. The device also supports different sequencing and sequencing control functions that allow the device to transition between two separate output voltages. This allows the device to start up from any output voltage, or default to a preferred output voltage. This provides a flexible and efficient power supply for a variety of different applications.

Application Field

The TC1303B-DF0EMFTR is suitable for a wide range of applications including battery-powered systems, portable devices, wireless medical devices, industrial control systems, and automotive systems. It can also be used for a broad range of applications requiring battery back-up power with low quiescent current.

Working Principle

The TC1303B-DF0EMFTR consists of two separate linear regulators (LDO) and a high-efficiency switching buck regulator. The two LDO regulators can provide up to 240mA of output current each and have an adjustable output voltage range of 0.8V to 8.0V. The buck converter can provide up to 500mA of output current, with a wide input battery range of 2.5V to 5.5V, and a switching frequency of 1.2MHz.

The device also features a wide range of features including fault protection, sequencing and sequencing control, on-off control, and power-down control. It also supports adjustable output voltage settings, allowing users to easily modify their settings based on their application requirement.

The TC1303B-DF0EMFTR operates by quickly converting the input voltage from the battery, to an appropriate output voltage set by the user. The device is able to simultaneously provide power to two separate rails, the LDO output and the buck output. The two LDO regulators have an adjustable output voltage, while the buck converter will always provide the set voltage as long as the output current is below the set maximum.

When the device is shut down, it will automatically drop the output voltage to zero and shut off the power to the rails. This prevents any damage to the load that may be powered by the device.
