TC1313-ZI0EMF

Overview

The TC1313-ZI0EMF is a dual-output power management IC from Microchip Technology, integrating a PWM synchronous buck regulator and an LDO. It features two positive outputs: one adjustable fixed output capable of delivering up to 500 mA, and another adjustable output providing up to 300 mA. The device operates within an input voltage range of 2.7 V to 5.5 V. Key electrical parameters include a quiescent current of 57 uA, dropout voltages of 205 mV and 280 mV for the respective channels, and an operating temperature range from -40°C to +85°C. It is housed in a DFN-10 surface-mount package.

Feature Summary

• Integrates a 500 mA synchronous buck converter with a 300 mA low-dropout linear regulator on a single chip.
• Provides flexible power delivery through one fixed and one adjustable output channel.
• Includes a Power Good monitor function to indicate valid output regulation status.

Applications

• Cellular phones and mobile communication devices
• Portable computers and laptops
• USB-powered peripheral devices
• Handheld instruments and measurement tools

Procurement Notes

Verify the specific suffix against the official Microchip datasheet to confirm pinout compatibility and thermal characteristics. Ensure the DFN-10 footprint matches your PCB layout requirements. Confirm RoHS compliance status via the manufacturer's environmental documentation before finalizing component selection for production.

Selection Notes

Select this component when space-constrained designs require both efficient switching regulation and clean linear regulation. The integrated solution reduces bill-of-materials count compared to discrete implementations. Consider the 57 uA quiescent current for battery life optimization in portable applications requiring multiple voltage rails.

Part Context

This part belongs to the TC13xx series of PMICs designed for high integration in portable electronics. It replaces separate buck and LDO components, simplifying circuit design. The DFN-10 package offers thermal efficiency suitable for dense PCB layouts common in modern consumer electronics and industrial handheld devices.
