The ET8215 is a high-frequency Boost DC-DC converter designed to deliver a regulated 5V output from a 2.7V to 4.8V input. Capable of supplying up to 1A of load current, it operates at a 2.5MHz switching frequency, enabling the use of tiny, low-profile inductors and capacitors. This makes it an excellent choice for space-limited, battery-powered applications requiring a stable 5V rail.
- Compact Solution Size: 2.5MHz switching frequency allows for small external components, reducing PCB footprint.
- Wide Input Range: Accepts 2.7V to 4.8V, covering single-cell Li-Ion and 3V battery chemistries.
- Stable 5V Output: Provides a fixed 5V rail essential for USB and logic circuits.
- High Efficiency: Optimized for battery-powered systems to maximize operational life.
Battery-Powered Portable Devices
Boost 2.7V-4.8V battery input to a stable 5V rail for USB-powered peripherals, portable audio, and handheld instruments. The 2.5MHz frequency allows for small external components, saving board space.
Single-Cell Li-Ion to 5V USB
Generate a regulated 5V bus from a single Li-Ion cell (3.0V-4.2V) for charging or powering small USB devices. The 1A current capability supports many low-power USB loads.
IoT Sensor Nodes
Power wireless sensors and microcontrollers from a 3V coin cell or AA battery. The high efficiency at light loads extends battery life in always-on monitoring applications.
Wearable Electronics
Compact WLCSP package and high-frequency operation make the ET8215 ideal for space-constrained wearables needing a 5V rail for displays or haptic drivers.
Portable Medical Devices
Provide a stable 5V supply for glucose meters, pulse oximeters, and other battery-operated medical monitors, ensuring consistent performance over the battery discharge curve.
