TC1313-DG0EMF

Overview

The TC1313-DG0EMF is a dual-output power management IC from Microchip Technology, integrating 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 features a total quiescent current of 57 µA typical. The buck converter supports adjustable output voltages from 0.8 V to 4.5 V or standard fixed outputs including 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. It utilizes a 2.0 MHz fixed-frequency PWM control mode under heavy loads and transitions automatically to PFM for efficiency. The LDO output is factory-set to 2.9 V. Both regulators are internally compensated and feature independent shutdown controls.

Feature Summary

• Integrates a 500 mA synchronous buck regulator and a 300 mA LDO in a single package
• Provides independent shutdown control for both the buck and LDO outputs
• Features automatic transition between PWM and PFM modes for optimized efficiency
• Includes internal compensation for both output channels

Applications

• Portable consumer electronics requiring multiple voltage rails
• Battery-powered devices needing efficient power conversion
• Embedded systems utilizing microprocessors or memory components

Procurement Notes

Verify the specific suffix DG0EMF to confirm the LDO output voltage is set to 2.9 V, as other suffixes indicate different fixed voltages. Ensure the order quantity matches the manufacturer's reel packaging requirements if purchasing in bulk. Confirm RoHS compliance status through official datasheets prior to final procurement decisions.

Selection Notes

Select this component when a compact solution is required for generating two distinct voltage levels from a single 3.6 V source. The integrated design reduces board space compared to discrete solutions. Consider the 2.0 MHz switching frequency for minimizing external passive component size while maintaining stable regulation under varying load conditions.

Part Context

This part belongs to the TC1313 family of dual-output regulators designed for space-constrained applications. The DFN-10 package provides a small footprint suitable for dense PCB layouts. The device is manufactured by Microchip Technology and is intended for commercial temperature ranges.

Replacement Considerations

Other variants within the TC1313 series may serve as substitutes if the LDO output voltage requirement differs. Verify pin compatibility and thermal characteristics before replacing with alternative models.
