Overview
The DCP3601CDMR is a synchronous step-down converter manufactured by STMicroelectronics, housed in a SOT-23-6 package. It supports an input voltage range of 3.3 V to 36 V and delivers up to 1 A output current. The device operates at a fixed switching frequency of 1 MHz with a typical quiescent current of 110 μA. It features adjustable output voltage starting from 0.85 V, peak current mode control, and internal compensation. Operating junction temperature ranges from -40°C to +150°C.
Feature Summary
- Synchronous rectification architecture for high efficiency
- Peak current mode control with internal compensation network
- Integrated protection including thermal shutdown and overvoltage protection
- Optional switching frequency dithering for improved EMI performance
Applications
- Industrial applications requiring wide input voltage range
- Space-constrained designs utilizing compact SOT-23-6L packaging
- Systems optimized for low-power consumption modes
Procurement Notes
Verify the specific suffix 'C' against official datasheets to confirm exact electrical characteristics and availability status. Confirm package type matches SOT-23-6 requirements. Check RoHS compliance details directly from manufacturer documentation before integration into final product designs.
Selection Notes
Select this component for applications demanding high integration within small footprints. Consider the 1 MHz frequency for smaller passive components. Evaluate thermal management needs given the 150°C maximum junction temperature rating. Ensure input voltage stays within the 3.3 V to 36 V operational window.
Part Context
Part of the DCP3601 series of versatile synchronous step-down converters. Designed for industrial use cases requiring robust performance. Offers variants like LCM for light load efficiency and LNM for noise-sensitive environments. Supports evaluation via STEVAL-3601CV1 board.
Replacement Considerations
Consult official substitution lists for direct equivalents. Verify pin compatibility and electrical parameters match exactly. No public confirmed substitute part numbers are identified in available documentation.
