The TC1303C-VP0EMFTR is a complete, integrated, low power, high performance power supply system. It combines a programmable buck regulator and linear regulators in a single package, leveraging the best of both linear and switch mode operation. This power supply system is ideal for portable electronics, as its low power consumption gives superior energy efficiency and improved battery life. The TC1303C-VP0EMFTR has one two-channel buck, one two-channel boost, one two-channel LED driver, and one LDO. With this array of features, it is obvious that the TC1303C-VP0EMFTR can achieve significant system optimization.

The TC1303C-VP0EMFTR is designed to be used in an array of application fields. Its battery charging functionality supports all major battery chemistries, including NiCd, NiMH, Li-Ion, and Li-Polymer, making it suitable for a variety of consumer and industrial products. The built-in switching power supply can be tuned for efficiency, making it ideal for low power mobile devices. The LED driver can be used to light up various configurations of LEDs, making it an invaluable tool for the lighting market. Additionally, the integrated LDO can be used to power I/Os, providing system designers with an added layer of flexibility.

The TC1303C-VP0EMFTR’s programmable buck and linear regulators adopt a Single-Ended Primary Inductance Converter (SEPIC) topology, maximizing efficiency in low power operations. The boost regulator acts as a multiple-output voltage source, which combines an integrated synchronous rectifier (pFET) and a power switch (nFET). The buck regulator operates in a voltage buck-mode, and the integrated synchronous rectifier allows for higher efficiency operation. The buck-boost regulator uses both the buck and boost modes to produce a regulated output from an input voltage of 1.8 V to 6.5 V. The LED driver regulates the forward voltage of LEDs to achieve optimal brightness levels. The LDO is used for supplying power of I/O.

The TC1303C-VP0EMFTR is designed for thermal, electrical and environmental considerations. The synchronous rectifiers are low on-resistance, they are integrated into the power switch, which eliminates the need for external components and reduces solution size. It also has output protection: OVP, OCP, VLO, UVLO, and Soft start. In addition, the device is built around a highly efficient switching architecture and capable of over 96% peak efficiency. As noted above, the integrated LDO efficiently supplies power of I/Os.

The TC1303C-VP0EMFTR is a versatile, low power and highly efficient programmable buck and linear converter. With its efficient buck and boost converters, LED drivers and LDO, this device offers an immense amount of system optimization and can be used in a wide range of applications. Its low power performance and features like OVP, OCP, VLO, and UVLO provide the perfect combination of performance, safety and cost for virtually any system.
