This article will discuss the application field and workings principle of the TC1303C-PI0EMFTR, a linear and switching PMIC (power management integrated circuit) voltage regulator. First, the application field of this voltage regulator will be discussed in detail. Then, its operating principle and particular features will be examined.

Application Field

The TC1303C-PI0EMFTR is used as a power management integrated circuit to provide a highly accurate regulated voltage output. It can provide a regulated output of 1.5V to 5.5V over a wide input voltage range of 2.5V to 5.5V with minimum load conditions of 500mV to 1.5V. This PMIC is ideal for applications that require low noise and high accuracy, such as cellular phones, cordless phones, and personal digital assistants. It is also suitable for other applications that require a high power drain such as printers, PDAs, and copier/fax devices.

Working Principle

The TC1303C-PI0EMFTR works by using a voltage divider to achieve the desired output voltage. The key components of the circuit are the feedback resistor, Rfb, the voltage reference, VR, and the duty-cycle control block. Rfb is connected between ground and the output of the regulator. Its purpose is to provide feedback for the regulator to adjust the duty-cycle of the internal oscillator to achieve the correct output voltage.VR is a precision voltage reference that provides a reference voltage to the duty-cycle control block. The duty-cycle control block then adjusts the duty-cycle of the oscillator so that the output voltage is equal to the voltage reference. The duty-cycle control block also makes sure that the output voltage is within the minimum and maximum output voltage range by continuously monitoring the output voltage and making adjustments when needed.

Features

The TC1303C-PI0EMFTR voltage regulator has some unique features that make it stand out from other PMICs and linear regulators. First, it has a very low operating current of 1uA. This makes the TC1303C-PI0EMFTR ideal for applications that require low power and maximum efficiency. Secondly, this PMIC uses a continuous bandgap reference with a minimum temperature coefficient of 20ppm/°C, allowing for very accurate regulation of the output voltage over wide temperature ranges. The TC1303C-PI0EMFTR also has an internal over-voltage and reverse-voltage protection circuit, which prevents damage to the IC and the components connected to it.

In addition, the TC1303C-PI0EMFTR also has a low output voltage drop of 40mV, allowing for better efficiency in low power applications. It also does not need any external components for operation, making it small, light, and easy to use. Lastly, the TC1303C-PI0EMFTR also has a shutdown mode, where the output voltage can be quickly switched off in case of emergency.

Conclusion

In conclusion, the TC1303C-PI0EMFTR PMIC voltage regulator is designed for applications that require low power, low noise and high accuracy. Its low operating current of 1uA, continuous bandgap reference and internal voltage protection features make it an excellent choice for applications such as cellular phones, cordless phones, PDAs and other devices that require a highly accurate output voltage. Its low output voltage drop and lack of external components are also beneficial, as they make it small, light, and easy to use.
