The power input voltage is 0.13V - 3V! Energy harvesting continues even when VIN drops to 130mV.
We would like to introduce our power management board, the 'VK-PM-5V'. This circuit board is designed to collect and manage power ranging from microwatts (μW) to milliwatts (mW) generated from various DC power sources such as photovoltaic cells and thermoelectric generators. This unit implements a high-efficiency boost converter/charger for products and systems with stringent power and operational requirements. 【Features】 ■ Ultra-low power consumption, high-efficiency DC-DC boost converter/charger ■ Continuous energy harvesting from low voltage input power sources: VIN ≥ 130mV (standard) ■ Ultra-low quiescent current: IQ < 330nA (standard) ■ Cold start voltage: VIN ≥ 330mV (standard) ■ Programmable dynamic maximum power point tracking (MPPT) *For more details, please refer to the PDF document or feel free to contact us.

Company information
I established this research institute with the aim of commercializing the chemical film formation technology I developed while working at the university. Along with the fabrication of related devices, I aim to develop a new dye-sensitized solar cell system that utilizes various films produced by this technology, contributing to energy supply and environmental conservation. I intend for all products to achieve the highest standards in the world.
