Overview
The TC1313-ZA0EMF is a dual-output power management integrated circuit manufactured by Microchip Technology, housed in a 10-pin DFN-10 package. It integrates a 500 mA synchronous buck regulator and a 300 mA Low-Dropout Regulator (LDO). The device operates within an input voltage range of 2.7 V to 5.5 V. The LDO output is fixed at 1.5 V with a typical dropout voltage of 137 mV at 200 mA. The total quiescent current is typically 57 µA. Operating junction temperature ranges from -40°C to +125°C.
Feature Summary
- Combines a 500 mA synchronous buck regulator and a 300 mA low-dropout linear regulator for efficient multi-voltage generation.
- Features independent shutdown control for both the buck and LDO outputs to manage power consumption.
- Includes automatic transition between PWM and PFM modes to optimize efficiency across varying load conditions.
Applications
- Cellular phones
- Portable computers
- USB-powered devices
- Handheld medical instruments
Procurement Notes
Verify the specific suffix ZA0EMF against official Microchip documentation to confirm the fixed LDO output voltage configuration. Ensure the required package type matches the DFN-10 footprint. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental declaration before finalizing procurement specifications.
Selection Notes
Select this component when a single IC solution is needed to generate a processor core voltage via the buck converter and a bias voltage via the LDO. Consider the 57 µA quiescent current for battery life requirements. Verify that the 500 mA buck and 300 mA LDO current ratings meet the system's peak load demands without exceeding thermal limits.
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 configurations to suit different voltage rails. The Z suffix indicates a specific fixed output voltage variant for the LDO section, distinguishing it from adjustable or other fixed voltage options within the same package.
Replacement Considerations
Check Microchip's official cross-reference lists for verified substitutes. Ensure any replacement maintains the 10-pin DFN-10 footprint and compatible electrical characteristics for direct integration.
