DC6M603X6/15A,135

Overview

The DC6M603X6/15A,135 is a highly efficient DC/DC step-down converter from the NXP DC6M4/5/6 series. It operates with a fixed 6 MHz switching frequency, enabling the use of small inductors to minimize board space. The device features an ultra-low output voltage ripple of typically 7 mV and supports an input voltage range of 2.3 V to 5.5 V. It provides a fixed 1.5 V output at up to 650 mA load current. Key electrical characteristics include a low quiescent current of 0.2 µA in shutdown mode and high conversion efficiency of up to 95%. The component includes built-in protection against inrush current, short circuits, and over-temperature conditions.

• Ultra-low output voltage ripple performance for sensitive analog loads
• Optimized for mobile and battery-driven devices with high efficiency
• Integrated protection mechanisms for inrush, short circuit, and temperature

Applications

• Mobile phone power management
• Battery-powered consumer electronics
• Portable IoT sensor nodes

Procurement Notes

Verify the specific suffix '135' indicates reel packaging when sourcing. Confirm the output voltage variant matches the design requirement, as the DC6M603 series includes different fixed output options. Ensure the WLCSP6 package footprint aligns with the PCB layout specifications. Check for RoHS compliance documentation if required by the manufacturing process. Validate that the 6 MHz switching frequency does not interfere with nearby RF circuits in the final assembly.

Selection Notes

Select this component when board space is constrained due to its small WLCSP6 package size. Choose this regulator for applications requiring minimal output noise, leveraging its 7 mV typical ripple specification. Consider this part for systems operating within the 2.3 V to 5.5 V input range. Opt for this device if high efficiency is critical for extending battery life in portable equipment. Evaluate the 650 mA maximum output current to ensure it meets the peak load demands of the target application.
