TC1313-VD0EMF Application Field and Working Principle
TC1313-VD0EMF is a voltage regulator belonging to the Power Management ICs (PMICs) group. It is a Linear + Switching regulator with versatile power management capabilities.
Application field
TC1313-VD0EMF is an energy-efficient, ultra-low quiescent current linear + switching regulator designed to replace existing unregulated linear and FET-based voltage regulators. It has a wide input voltage range between 3V and 26V, and the output can be programmed to provide 1.4V to 17V with a 0.9V step, programmable current limit and soft-start function. This is a very versatile regulator and serves applicatoin from applications requiring light load efficiency to applications requiring high load performance.
Working principle
TC1313-VD0EMF is able to operate in three distinct modes; Linear only mode, switching only mode and adaptive linear+switching mode. In linear only mode, the voltage regulator will start up and maintain operation with a single pass element in a linear path, controlling the output voltage and simultaneously the output current with an adjustable resistor divider.
In switching only mode, a single high side N-channel MOSFET and a PWM mode switching control is used to regulate the output voltage and current. The switching frequency is designed to be very low, providing a smooth, low ripple, low noise voltage source.
The adaptive linear+switching mode is the regulator’s most efficient operation mode, where the output voltage is regulated in a hybrid of the two modes. The regulator will switch between the two modes autonomously in low and high load conditions, offering higher efficiency and improved transient response.
Conclusion
TC1313-VD0EMF is a versatile power management IC belonging to the PMIC - Voltage Regulators - Linear + Switching category. This is a high efficiency, low quiescent current regulator offering wide input voltage range and output voltage programmability, adjustable current limit and soft-start functionality. This regulator operates in three distinct modes depending on the applied load, allowing it to find the most efficient operating mode to maintain the desired voltage.
