TC1313-ZG0EMF

Overview

The TC1313-ZG0EMF is a dual-output power management IC from Microchip Technology, featuring a 500 mA synchronous buck regulator and a 150 mA low-dropout regulator (LDO). It operates within an input voltage range of 2.7 V to 5.5 V. The device utilizes current-mode control with pulse width modulation for the buck section and offers automatic PWM-to-PFM transition for efficiency optimization. The LDO provides fixed output voltages, while the buck output is adjustable from 0.8 V to 4.5 V or selectable via standard fixed options.

Feature Summary

• Integrates a 500 mA synchronous buck converter and a dedicated 150 mA LDO in a single package
• Provides independent shutdown controls for both the buck and LDO outputs to manage power states
• Features internal compensation for both regulators, simplifying external component requirements
• Supports automatic transition between PWM and PFM modes to maintain high efficiency across load ranges

Applications

• Portable battery-powered devices requiring multiple regulated voltage rails
• Embedded systems needing efficient step-down conversion alongside stable analog supply
• Industrial control modules with strict space constraints for power components
• Communication equipment utilizing mixed-signal architectures

Procurement Notes

Verify the specific suffix configuration against the official Microchip datasheet to ensure correct output voltage settings and packaging type. Confirm RoHS compliance status and lead times through authorized distributors. Check for any recent design changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a compact solution is required for generating two distinct voltage levels from a single input source. The integrated nature reduces board space compared to discrete solutions. Ensure the total quiescent current and thermal performance under expected load conditions meet system requirements. Verify that the fixed LDO output voltage aligns with the target application needs.

Part Context

This part belongs to the TC1313 family of dual-output regulators designed for space-constrained applications. It combines switching regulation with linear regulation to offer flexibility in power distribution. The DFN-10 package facilitates surface-mount assembly, supporting automated manufacturing processes common in modern electronics production lines.

Replacement Considerations

Direct substitutes include other TC1313 variants with different fixed output voltages, such as TC1313-ZP0EMF or TC1313-MB1EMFTR. Cross-reference pinouts and electrical characteristics carefully to ensure compatibility with existing circuit designs without modification.
