TC1313-ZP0EMFTR

Overview

The TC1313-ZP0EMFTR 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. The device features independent shutdown controls for both outputs and internally compensated loops. The buck converter supports adjustable output voltages from 0.8 V to 4.5 V or standard fixed settings, utilizing a 2.0 MHz PWM frequency with automatic transition to PFM mode for efficiency. The LDO provides a fixed 1.5 V output. Total quiescent current is typically 57 µA.

Feature Summary

• Integrates a high-efficiency synchronous buck regulator and a low-noise LDO in a single compact package
• Features independent shutdown control pins allowing separate management of the switching and linear regulator outputs
• Supports automatic transition between Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) modes to optimize light-load efficiency
• Includes internal compensation for both regulators, simplifying external component requirements

Applications

• Portable battery-powered devices requiring multiple regulated voltage rails
• Embedded systems needing efficient power conversion with low standby current consumption
• Applications requiring simultaneous generation of adjustable and fixed logic supply voltages

Procurement Notes

Verify the specific suffix ZP0EMFTR against official Microchip documentation to confirm the fixed 1.5 V LDO output configuration. Ensure compatibility with the required DFN-10 package dimensions and thermal characteristics. Confirm RoHS compliance status and lead-free specifications prior to integration into production designs.

Selection Notes

Select this component when a design requires a combined solution for high-current switching regulation and clean linear regulation. It is suitable for applications where board space is limited and independent output control is necessary. Consider the 2.0 MHz switching frequency for smaller passive component sizes compared to lower-frequency alternatives.

Part Context

This part belongs to the TC1313 family of dual-output regulators designed for portable electronics. The series offers various fixed and adjustable output combinations to suit different system architectures. The ZP0 variant specifically pairs the adjustable buck with a 1.5 V LDO, distinguishing it from other variants that may offer different fixed LDO voltages such as 1.8 V or 3.3 V.

Replacement Considerations

Other TC1313 variants with different LDO output voltages may serve as functional substitutes if the specific 1.5 V requirement can be adjusted via external resistors or if the application tolerates a different fixed voltage.
