The LM3370TL-3206/NOPB from National Semiconductor is a dual-output synchronous Buck DC-DC converter in an ultra-compact DSBGA package. It operates from 2.7V to 5.5V and provides two fixed outputs: 1.3V and 1.8V, each rated for up to 600mA. The 2MHz switching frequency allows for very small inductors and capacitors, making it ideal for space-constrained portable devices. This converter is well-suited for application processors, wearables, and wireless modules requiring multiple low-voltage rails.
- Ultra-Small Package: 20-WFBGA DSBGA package is ideal for wearables and compact designs.
- Dual Fixed Outputs: 1.3V and 1.8V rails are optimized for processor and memory power.
- High Switching Frequency: 2MHz reduces external component size significantly.
- Battery-Friendly: 2.7V to 5.5V input range covers single-cell Li-ion applications.
