The LM3370SD-3021/NOPB from National Semiconductor is a dual-output Buck DC-DC converter designed for battery-powered portable electronics. Operating from a 2.7V to 5.5V input, it provides regulated 1.2V and 3.3V outputs, each capable of sourcing up to 600mA. The fixed 2MHz switching frequency allows for small external components, while the 16-WFDFN exposed pad package ensures efficient thermal performance. This converter is an excellent choice for powering dual-rail systems in smartphones, wearables, and other compact devices.
- Dual Outputs: Provides 1.2V and 3.3V rails from a single IC, reducing component count and PCB area.
- Low Input Voltage: Operates down to 2.7V, maximizing usable battery capacity.
- High Switching Frequency: The 2MHz frequency enables the use of tiny inductors and capacitors, ideal for space-constrained designs.
- Efficient Power Conversion: Buck topology ensures high efficiency, extending battery life in portable devices.
Portable Media Players
The dual outputs (1.2V for core, 3.3V for I/O) from a single 2.7V-5.5V input make this converter ideal for powering application processors and memory in portable media players, simplifying the power supply design.
Smartphones and Tablets
In mobile devices, the LM3370SD-3021/NOPB efficiently provides separate voltage rails for digital cores and analog peripherals, ensuring stable operation while maximizing battery life.
Wireless Headsets and Wearables
With its low 2.7V minimum input, this buck converter can operate from a nearly depleted Li-Ion battery, providing regulated 1.2V and 3.3V rails for Bluetooth SoCs and sensor hubs.
Digital Cameras
The dual outputs can power both the image sensor (3.3V) and the DSP core (1.2V), reducing the number of separate regulators needed and saving board space in compact camera modules.
Handheld GPS Units
For GPS navigation devices, this converter provides a stable 3.3V rail for the display and GPS receiver, and a 1.2V rail for the main processor, all from a single battery source.
