TC1313-1P0EMFTR

Overview

The TC1313-1P0EMFTR is a dual-output power management IC from Microchip Technology, featuring 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 utilizes a DFN-10 package with dimensions of 3 mm x 3 mm. Key electrical parameters include a typical quiescent current of 57 µA and a fixed switching frequency of 2.0 MHz for the buck converter. The LDO output is fixed at 1.0 V, while the buck output provides standard voltages such as 1.2 V.

Feature Summary

• Integrates a 500 mA synchronous buck regulator and a 300 mA LDO in a single compact package.
• Features independent shutdown control for both the buck and LDO outputs to optimize system power consumption.
• Includes automatic transition between PWM and PFM modes to maintain high efficiency across varying load conditions.

Applications

• Portable consumer electronics requiring efficient multi-rail power distribution
• Battery-powered devices needing extended operational time through low quiescent current
• Embedded systems utilizing microcontrollers or application processors with distinct core and I/O voltage requirements

Procurement Notes

Verify the specific suffix '1P0' confirms the 1.0 V LDO output configuration against the official datasheet before ordering. Ensure the DFN-10 package footprint matches the target PCB layout design. Confirm RoHS compliance status and check for any lead time variations directly with the manufacturer or authorized distributors.

Selection Notes
