In-Depth Product Analysis
Technical Specifications
- Input Range: 2V-6V (supports Li-ion batteries & low-voltage sources)
- Output: Fixed 1.8V 2% accuracy at 600mA max current
- Peak Efficiency: 90% (typical at 3.6V input, 1.8V output)
- Quiescent Current: Only 15 A in standby mode
- Switching Frequency: 1.2MHz (enables compact external components)
Package Details
The 6-pin DFN package (2.5 2.0 1.0mm) features an exposed thermal pad for enhanced heat dissipation in high-density PCB layouts. The ultra-thin 1mm profile makes it ideal for portable electronics.
Performance Advantages
Advanced Power Management
Incorporates Torex's proprietary Auto-Skip Control technology that automatically switches between PWM and PFM modes to maintain high efficiency across load ranges (10 A to 600mA).
Reliability Features
- Built-in soft-start (100 s typical) prevents inrush current
- Over-current and thermal shutdown protection
- 2% output voltage accuracy over full temperature range
Design Considerations
Recommended Layout
For optimal performance:
- Place input capacitors within 1mm of VIN pin
- Use minimum 0.3mm trace width for power paths
- Connect thermal pad to PCB ground plane with multiple vias
