Nexperia Announces New Ultra-Low Quiescent Current Step-Down DC-DC Converter Integrated Circuits
Nexperia Launches NEX30606: Ultra-Low Quiescent Current Step-Down Converter for Battery-Powered Applications
Nexperia, a global leader in semiconductor solutions, has introduced the NEX30606, a high-efficiency step-down converter characterized by an ultra-low quiescent current of just 220 nA. This exceptionally low quiescent current makes the NEX30606 ideally suited for battery-powered applications where minimizing power consumption is paramount, such as wearable electronics, smart meters, and medical sensor patches.
Key Features and Benefits of the NEX30606:
- Ultra-Low Quiescent Current: Consumes only 220 nA of current when not actively switching, significantly extending battery life in low-power applications.
- Wide Input Voltage Range: Supports input voltages from 1.8 V to 5.0 V, accommodating various battery chemistries and configurations, including 2S to 3S alkaline batteries, 1S Li-MnO2, Li-ion, and Li-SOCL2.
- High Output Current Capability: Delivers up to 600 mA of output current, sufficient for powering a variety of low-power devices.
- High Efficiency: Achieves over 90% efficiency at a 1 mA load and exceeds 92.8% efficiency at a 300 mA load, particularly in configurations like a 3.6 V input to 1.8 V output.
- Constant On Time (COT) Control: Utilizes COT control for minimal power consumption and rapid transient response to load changes.
- Power Save Mode: Automatically enters Power Save Mode at light loads, further reducing switching cycles and maximizing battery life.
- Flexible Output Voltage: Offers 16 selectable fixed output voltages, configurable via the VSET pin, with a 2% output voltage accuracy.
- Ultra-Compact Package: Available in the ultra-compact WLCSP6 (SOT8055-1) package with a 0.35 mm pitch, making it ideal for space-constrained designs.
- Robust Protection Features: Includes built-in output discharge and ESD protection, meeting industry standards:
- HBM (Human Body Model): ANSI/ESDA/JEDEC JS-001 Class 2, exceeding 2000 V
- CDM (Charged Device Model): ANSI/ESDA/JEDEC JS-002 Class C2a, exceeding 500 V
- Wide Operating Temperature Range: Designed for reliable operation across an extended temperature range from -40°C to +125°C, making it suitable for industrial environments and harsh operating conditions.
Target Applications Across Multiple Industries:
The NEX30606 is ideally suited for a wide range of power-sensitive applications across various industries:
