TC1304-VI0EMFTR

Overview

The TC1304-VI0EMFTR is a dual-output power management integrated circuit manufactured by Microchip Technology. It integrates a 500 mA synchronous buck regulator and a 300 mA low-dropout (LDO) linear regulator within a single DFN-10 package measuring 3 x 3 mm with a height of 0.9 mm. The device operates with an input voltage range from 2.7 V to 5.5 V, featuring a typical quiescent current of 65 µA. The switching regulator supports a fixed frequency of 2.0 MHz and includes automatic transition between PWM and PFM modes for optimized efficiency across load conditions.

Feature Summary

• Integrates a 500 mA synchronous buck regulator and a 300 mA LDO in a compact footprint
• Features a Power-Good output signal with a 300 ms delay for system monitoring
• Supports automatic transition from Pulse Width Modulation to Pulse Frequency Modulation for improved light-load efficiency
• Includes internal compensation for both regulator outputs to simplify external component requirements

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• USB-powered equipment and peripherals
• Handheld instruments and personal digital assistants
• Battery-operated consumer electronics

Procurement Notes

Verify the specific suffix VI0EMFTR against official Microchip documentation to confirm the exact output voltage configuration and revision level. Ensure compatibility with the target PCB footprint, specifically the 3x3mm DFN-10 package dimensions. Confirm that the operating temperature range meets the application requirements before finalizing procurement orders.

Selection Notes

Select this component when a design requires two distinct regulated outputs from a single IC to minimize board space. It is suitable for applications needing a high-current switching rail alongside a low-noise linear supply. Consider the 2.0 MHz switching frequency for balancing component size against electromagnetic interference constraints.

Part Context

This part belongs to the TC1303/TC1304 series of dual-output regulators designed for portable applications. The series combines switching and linear regulation technologies to provide efficient power management solutions. The TC1304 variant specifically focuses on delivering stable power for systems requiring both high current and low noise capabilities within a small form factor.

Replacement Considerations

Consult Microchip datasheets for direct pin-compatible alternatives within the TC1303 or TC1304 families. Verify that any substitute maintains the same DFN-10 package and electrical characteristics, particularly the 500 mA buck and 300 mA LDO current ratings.
