TC1313-ZS0EMFTR

Overview

The TC1313-ZS0EMFTR is a dual-output power management IC from Microchip Technology, integrating 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. 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 fixed outputs including 0.8 V, 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 scheme with automatic transition to PFM mode for light loads. The LDO provides a fixed output voltage of 2.8 V. Both outputs 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
• Features independent shutdown controls for both the buck and LDO outputs
• Provides automatic transition between PWM and PFM modes for optimized efficiency
• Includes internal compensation for both output regulators

Applications

• Portable battery-powered electronic devices
• Embedded systems requiring multiple regulated voltage rails
• Consumer electronics with space-constrained designs
• Industrial control modules needing efficient power conversion

Procurement Notes

Verify the specific suffix 'ZS' corresponds to the 2.8 V fixed LDO output configuration when ordering. Confirm that the 'TR' suffix indicates tape-and-reel packaging suitable for automated assembly processes. Ensure compatibility with DFN-10 surface-mount footprint requirements during PCB layout planning. Cross-reference the manufacturer's latest datasheet to validate environmental compliance and operating temperature ranges before finalizing procurement specifications.

Selection Notes

Select this component when a compact solution is required to generate two distinct voltage rails from a single input source. It is suitable for applications demanding high efficiency under heavy loads due to the synchronous buck topology. Consider this part if independent control of power states for different system sections is necessary. Evaluate the 57 µA quiescent current against standby power requirements to ensure it meets system-level energy efficiency targets.

Part Context

This part belongs to the TC1313 family of dual-output regulators designed by Microchip Technology. The family combines switching and linear regulation technologies to maximize efficiency while maintaining low noise performance. Variants within the series differ primarily in the fixed output voltage of the LDO section or the programmable settings of the buck converter. The DFN-10 package allows for small form factor implementations in modern portable electronics.

Replacement Considerations

Direct substitutes include other TC1313 variants with different LDO fixed voltages, such as TC1313-TC3EMFTR (3.1 V LDO), TC1313-OS3EMFTR (1.5 V LDO), TC1313-UD0EMFTR (3.0 V LDO), TC1313-TP3EMFTR (1.8 V LDO), TC1313-UM0EMF (2.1 V LDO), TC1313-NH3EMFTR (2.6 V LDO), and TC1313-OQ0EMF (1.7 V LDO). Verify that the alternative part's LDO output voltage matches the target circuit requirement.
