The ET82099 from ETEK MICROELECTRONICS is a versatile Boost DC-DC converter designed for ultra-low voltage energy harvesting applications. It accepts an input from 0.7V to 5.5V and provides an adjustable output from 1.8V to 5.5V with up to 800mA switch current. The 6-UFBGA WLCSP package is extremely compact, making it ideal for space-constrained IoT and wearable devices. Its ability to start from just 0.7V makes it perfect for solar or thermoelectric energy harvesting.

  • Ultra-Low Startup Voltage (0.7V): Enables energy harvesting from solar, thermoelectric, or nearly depleted batteries.
  • Wide Input/Output Range: Flexible for various battery chemistries and load requirements.
  • 800mA Switch Current: Supports moderate power loads.
  • Compact 6-UFBGA Package: Minimizes PCB area for miniaturized designs.

Single-Cell Solar Harvesting

Boost the low voltage (0.7V) from a small solar cell to a usable 1.8V-5.5V rail for IoT sensors. The ultra-low startup voltage enables energy harvesting in low-light conditions.

Alkaline Battery Powered Devices

Use the wide input range (0.7V-5.5V) to extract energy from nearly depleted alkaline batteries, extending device runtime.

Wearable Health Monitors

Boost a coin cell battery (1.5V-3V) to power a sensor hub and Bluetooth LE module. The small WLCSP package fits in compact wearables.

Portable Instrumentation

Generate a stable 3.3V or 5V rail from a single-cell battery for multimeters or handheld test equipment.

RFID Tags

Boost the harvested RF energy to power a microcontroller. The low startup voltage is critical for passive tag operation.

Emergency Backup Power

Use a supercapacitor (0.7V-2.5V) as a backup source to maintain a regulated output during main power loss.
