TC1313-1P0EMF

Overview

The TC1313-1P0EMF is a dual-output power management IC from Microchip Technology, combining 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 output is fixed at 1.0 V, while the LDO output is fixed at 1.8 V. Both outputs are internally compensated and support independent shutdown. The component is housed in a DFN-10 package.

Feature Summary

• Integrates a 500 mA synchronous buck converter with a 300 mA LDO for efficient dual-rail power generation
• Features automatic transition between PWM and PFM control modes to optimize efficiency across load conditions
• Provides independent shutdown controls for both the buck and LDO outputs to manage power states
• Includes internal compensation for both regulators to simplify external component requirements

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Battery-powered systems needing high efficiency and low quiescent current
• Embedded applications utilizing single-cell lithium-ion or lithium-polymer batteries
• Consumer electronics with space-constrained PCB layouts

Procurement Notes

Verify the specific suffix '1P0' confirms the fixed 1.0 V buck output during procurement. Confirm the DFN-10 package type matches the target footprint. Ensure RoHS compliance documentation is available if required by project specifications. Check manufacturing lead times as availability may vary. Validate that the operating temperature range meets environmental requirements.

Selection Notes

Select this component when a compact solution is needed for generating two distinct voltage levels from a single input source. The fixed 1.0 V buck output suits digital logic cores, while the 1.8 V LDO serves analog peripherals. Consider the 57 µA quiescent current for battery life optimization. Verify that the 500 mA buck capacity meets peak load demands without excessive thermal dissipation in the DFN-10 package.
