TC1304-ZP0EMF

Overview

The TC1304-ZP0EMF 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 linear regulator (LDO) within a single DFN-10 package. The device operates with an input voltage range of 2.7 V to 5.5 V. The synchronous buck converter supports adjustable output voltages from 0.8 V to 4.5 V or standard fixed outputs, featuring automatic transition between PWM and PFM modes for optimized efficiency. The LDO provides stable regulation with low quiescent current.

Feature Summary

• Integrates a 500 mA synchronous buck regulator and a 300 mA LDO in a compact footprint
• Features automatic transition between pulse width modulation and pulse frequency modulation modes
• Includes a power-good output indicator with a specified delay time
• Supports independent shutdown control for the buck and LDO outputs

Applications

• Portable consumer electronics requiring multi-voltage rails
• USB-powered peripheral devices
• Battery-operated handheld instruments
• Embedded systems with space-constrained power designs

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm output voltage configuration and package variant. Ensure compatibility with required thermal dissipation standards for the DFN-10 housing. Confirm RoHS compliance status through the manufacturer's latest datasheet revision. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a design requires both high-efficiency switching regulation and low-noise linear regulation in a single package. The integrated power-good signal simplifies system sequencing logic. Consider the maximum input voltage limit and thermal performance under heavy load conditions. Verify that the available fixed or adjustable output ranges meet the target rail requirements without external feedback adjustments.

Part Context

This part belongs to the TC1303/TC1304 series of dual-output regulators designed for portable applications. The series combines switching and linear technologies to maximize battery life while maintaining clean power delivery. The ZP0EMF suffix indicates a specific reel-packaged variant within the broader product family, sharing core electrical characteristics with other TC1304 models.

Replacement Considerations

Direct replacements include other TC1304 variants with matching output configurations and pinouts. Verify functional equivalence regarding shutdown controls and power-good timing. Ensure substitute parts maintain the same DFN-10 footprint and thermal specifications.
