TC1313-PP0EMF

Overview

The TC1313-PP0EMF is a dual-output power management IC from Microchip Technology, featuring a 500 mA synchronous buck regulator and a 300 mA low-dropout (LDO) regulator. It operates within an input voltage range of 2.7 V to 5.5 V, with a nominal rating of 3.6 V. The device provides fixed output voltages of 1.8 V for both the buck and LDO channels. It utilizes current-mode control with pulse width modulation technology and is housed in a 10-pin DFN package measuring 3 x 3 mm with a height of 0.90 mm.

Feature Summary

• Integrates a 500 mA synchronous buck converter and a 300 mA LDO in a single compact package
• Provides independent shutdown control for each output channel to manage power states
• Features internal compensation for both regulators to simplify external component requirements
• Supports automatic transition between PWM and PFM modes to optimize efficiency across load conditions

Applications

• Portable consumer electronics requiring multiple stable voltage rails
• Battery-powered devices needing efficient power conversion and low quiescent current
• Embedded systems utilizing microcontrollers or sensors with specific 1.8 V logic levels
• Mobile communication modules requiring compact power solution footprints

Procurement Notes

Verify the exact part number against official Microchip documentation to confirm the fixed 1.8 V output configuration for both channels. Ensure compatibility with the required thermal dissipation characteristics of the DFN-10 package. Confirm that the 500 mA buck and 300 mA LDO current ratings meet the specific load demands of the target application design.

Selection Notes

Select this component when a combined switching and linear regulation solution is required to save board space. The fixed 1.8 V outputs are suitable for applications where these specific voltage levels are standard. Consider the total quiescent current specifications if battery life is a critical constraint. Verify that the input voltage range aligns with the available power source.

Part Context

This device belongs to the TC1313 family of dual-output regulators designed for space-constrained applications. It combines high-efficiency switching regulation with the clean output of an LDO. The family offers various fixed and adjustable output configurations to suit different system architectures while maintaining a consistent small footprint and control interface.

Replacement Considerations

Consult Microchip's official cross-reference data for verified substitutes. Ensure any replacement maintains the same 10-pin DFN package dimensions and pinout compatibility. Verify that alternative parts support the required 500 mA buck and 300 mA LDO current capabilities.
