Microchip Technology TC1303B-1H0EMFTR

The TC1303B-1H0EMFTR from Microchip Technology is a high-performance, integrated power management solution that combines a synchronous buck regulator with a linear regulator. This dual-output device is designed to provide a highly efficient and space-saving solution for a wide range of applications, particularly those requiring low power consumption and a compact footprint.

Key Features

• High-Efficiency Synchronous Buck Regulator: The integrated synchronous buck (step-down) regulator is capable of delivering up to 500 mA of continuous output current, which allows for efficient power conversion with reduced heat generation.
• Low-Dropout Linear Regulator: Alongside the buck regulator, a low-dropout (LDO) linear regulator provides up to 300 mA of output current, ensuring stable voltage supply even when input voltage is close to the output voltage.
• Wide Input Voltage Range: The device operates over a broad input voltage range from 2.7V to 5.5V, making it versatile for various supply sources, including single-cell Li-Ion batteries and 3.3V or 5V system rails.
• Adjustable Output Voltage: Both the buck and LDO regulators offer adjustable output voltages, allowing designers to tailor the power supply to the specific needs of their application.
• Power-Saving Modes: The TC1303B-1H0EMFTR features multiple power-saving modes, including automatic PWM/PFM switching, which helps to maintain high efficiency across a wide range of loads.
• Thermal Protection: Built-in thermal shutdown protection ensures the device operates within safe temperature limits, enhancing system reliability.
• Small Package Size: The device is available in a compact 10-pin MSOP package, which is ideal for space-constrained applications.
