UCC3585D

DC DC Switching Controllers Overview

The UCC3585D is a low-voltage synchronous buck controller from Texas Instruments designed for high-efficiency power conversion. It supports output voltages as low as 0.9 V and operates with a supply voltage between 3 V and 5.5 V. The device features a fixed switching frequency of 500 kHz and allows for duty cycles up to 100%. It is housed in a 16-SOIC package and functions within an operating temperature range of 0°C to +85°C.

DC DC Switching Controllers Feature Summary

• Provides flexible high-efficiency power conversion for low output voltages
• Supports 100% duty cycle operation for minimal voltage drop applications
• Integrates current limit, enable, frequency control, and soft start capabilities

DC DC Switching Controllers Applications

• Low-voltage power management in portable electronics
• IoT devices requiring efficient step-down regulation
• Systems utilizing 3V to 5.5V input supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (e.g., D vs. MTRG4) against the required package type and reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the component lifecycle status matches your production needs, as availability may vary by region or distributor.

DC DC Switching Controllers Selection Notes

Select this controller when designing synchronous buck converters that require operation at very low output voltages near 0.9 V. It is suitable for applications needing a fixed 500 kHz switching frequency and integrated protection features like soft start and current limiting within a standard surface-mount package.

DC DC Switching Controllers Part Context

The UCC3585D belongs to the UCC3585 family of low-voltage synchronous buck controllers. It is part of Texas Instruments' portfolio of PMIC solutions aimed at optimizing power efficiency in compact electronic designs. The device complements other switching controllers by offering specific low-voltage performance characteristics.

DC DC Switching Controllers Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the UCC3585MTRG4, noting differences in packaging and tape-and-reel specifications. Verify if newer generations offer improved thermal performance or extended lifecycle status.
