TC1303C-VP0EMFTR

Overview

The TC1303C-VP0EMFTR is a dual-output power management IC manufactured by Microchip Technology, featuring a 500 mA synchronous buck regulator and a 300 mA low-dropout (LDO) linear 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 utilizes current-mode control and pulse width modulation (PWM), supporting a maximum switching frequency of 2400 kHz. It transitions automatically from PWM to PFM mode for efficiency optimization. Packaged in a 10-pin DFN (HVSON) footprint measuring 3 x 3 mm with a height of 0.9 mm, it includes independent shutdown controls and a power-good output.

Feature Summary

• Integrates a 500 mA synchronous buck converter and a 300 mA LDO in a single compact package
• Provides independent shutdown functionality for both the buck and LDO outputs
• Features automatic transition between PWM and PFM modes to optimize efficiency across load conditions
• Includes a power-good output signal with a defined delay time

Applications

• Portable consumer electronics requiring efficient dual-rail power distribution
• Battery-powered devices utilizing lithium-ion or lithium-polymer cells
• Embedded systems needing isolated regulation for digital logic and analog peripherals

Procurement Notes

Verify the specific suffix VP0 against official Microchip documentation to confirm the exact fixed output voltage configuration. Ensure the ordering part number matches the required tape-and-reel packaging format. Confirm RoHS compliance status and lead-free terminal finish specifications prior to procurement to meet environmental standards.

Selection Notes

Select this component when space-constrained designs require simultaneous high-current buck conversion and low-noise LDO regulation. Consider the internal compensation which simplifies external component selection. Evaluate the thermal performance of the DFN package relative to the expected ambient temperature and load current requirements.

Part Context

This part belongs to the TC1303 family of dual-output regulators. Variants within this series differ primarily in their fixed output voltage settings and specific pin-out configurations for shutdown and enable functions. The 'C' designation typically indicates a specific revision or feature set within the product line.

Replacement Considerations

Direct replacements include other TC1303 variants such as TC1303C-TR1EMFTR or TC1303C-YO0EMFTR, provided the output voltage requirements match. Verify that the substitute part maintains the same DFN-10 package dimensions and pin compatibility.
