TC1313-1H0EUN

Overview

The TC1313-1H0EUN is a dual-output power management IC from Microchip Technology, featuring a 500 mA synchronous buck regulator and a 300 mA low-dropout regulator (LDO). 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 utilizes current-mode control and pulse width modulation, supporting a maximum switching frequency of 2400 kHz. It is housed in a 10-pin MSOP package.

Feature Summary

• Integrates a 500 mA synchronous buck converter and a 300 mA LDO for efficient dual-rail power generation.
• Provides independent shutdown control for both the buck and LDO outputs to optimize system power consumption.
• Features automatic transition between PWM and PFM modes to maintain high efficiency across varying load conditions.

Applications

• Portable consumer electronics requiring compact dual-voltage power solutions
• Battery-powered devices needing extended runtime through low quiescent current operation
• Embedded systems utilizing microprocessors or memory components with distinct voltage requirements

Procurement Notes

Verify the specific suffix 'EUN' confirms the MSOP-10 plastic package and standard operating temperature range. Confirm that the part number corresponds to the fixed 1.8V output variant as indicated by the code. Ensure compliance with RoHS standards and lead-free specifications required for your assembly process. Cross-reference the manufacturer's latest datasheet for any updates on moisture sensitivity levels or recommended soldering profiles.

Selection Notes

Select this component when a single-chip solution is needed to generate two regulated voltages from a single lithium-ion or lithium-polymer battery source. It is suitable for designs prioritizing board space reduction due to its small footprint. Consider the internal compensation which simplifies external component selection compared to non-compensated alternatives.

Part Context

This part belongs to the TC1313 family of dual-output regulators designed for portable applications. The family offers various fixed output voltages and packaging options, including DFN and MSOP. The TC1313 series is characterized by high efficiency and low noise, making it appropriate for sensitive analog and digital loads in mobile devices.

Replacement Considerations

Check for other TC1313 variants with different output voltages if the 1.8V specification does not match the design requirement. Verify pin compatibility with alternative packages like DFN-10 if layout changes are permissible. Consult Microchip documentation for direct cross-references or updated revisions of the same functional block.
