Overview
The DC6M603X6/12A,135 is a DC/DC switching converter manufactured by NXP Semiconductors. It functions as a buck step-down converter with a fixed output voltage of 1.2V and a maximum output current capability of 650mA. The device operates within an input voltage range of 2.3V to 5.5V and utilizes a 6MHz switching frequency. It is housed in a compact WLCSP-6 package (1.0mm x 1.4mm) designed for space-constrained mobile and battery-driven applications.
Feature Summary
- Ultra-low output voltage ripple performance
- Optimized efficiency across load ranges up to 95%
- Very small WLCSP6 package for board space reduction
Applications
- Mobile devices
- Battery-driven equipment
- Space-constrained consumer electronics
Procurement Notes
Verify the specific suffix '135' corresponds to the required tape-and-reel packaging configuration. Confirm that the fixed 1.2V output aligns with system power requirements, as this variant does not support adjustable voltage settings. Ensure compatibility with the specified WLCSP-6 footprint during PCB layout.
Selection Notes
Select this component when ultra-low output ripple is critical for sensitive analog circuits. The 650mA current rating suits moderate power loads. Consider the 6MHz frequency for minimizing passive component size. Verify thermal management capabilities within the small package for high-load scenarios.
Part Context
This part belongs to the DC6M4/5/6 series of 6MHz DC/DC step-down converters from NXP. These converters are engineered for high efficiency and minimal footprint, targeting portable electronics where battery life and board real estate are primary constraints.
Replacement Considerations
Check for other variants within the DC6M603X6 family offering different fixed output voltages if 1.2V is unsuitable. Verify availability of equivalent WLCSP-6 buck converters from other manufacturers if supply chain constraints exist.
