The TC1303B-IA0EMFTR is a highly integrated power management solution from Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This advanced component combines a high-speed, high-efficiency, fixed-frequency, pulse-width-modulated (PWM) step-down (buck) converter with an additional linear regulator to provide two regulated outputs from a single input power source.

Key Features

• Efficient Power Conversion: The buck converter operates at a fixed frequency of 2 MHz, allowing for a compact solution with small external components, thereby reducing the overall footprint on the printed circuit board (PCB).
• Dual Output: The device provides two outputs: a high-current channel from the buck converter and a lower current output from the linear regulator, making it suitable for applications requiring multiple regulated voltages.
• Low Quiescent Current: It features a low quiescent current, which enhances its suitability for battery-powered applications by extending battery life.
• Thermal Protection: The TC1303B-IA0EMFTR includes thermal shutdown protection that safeguards the device from damage due to excessive heat.
• Overcurrent Protection: Built-in overcurrent protection ensures that the device and the system are protected from damage in the event of output overload or short-circuit conditions.

Applications

This versatile component is ideal for a wide range of applications, including but not limited to:

• Portable and battery-operated devices
• Microcontroller/processor power supplies
• Standby and sleep power supplies
• Point-of-load power supplies in distributed power systems
