Product Description
The ROHM BD70522GUL-EVK-101 Buck Converter Evaluation Board is designed for detailed evaluation of the BD70522GUL buck converter IC, featuring an ultra-low quiescent current of 180nA and an output current capability of up to 500mA. This board employs Constant ON-Time (COT) control with an ultra-low power mode that achieves excellent light load efficiency below 10μA load range, extending battery life in portable applications.
The output voltage can be selected using VSEL pins offering nine preset voltages: 1.2V, 1.5V, 1.8V, 2.0V, 2.5V, 2.8V, 3.0V, 3.2V, and 3.3V. The device has built-in discharge function on VOUT, and it enters a 100% ON mode when the input voltage approaches the output voltage, ceasing switching to maximize efficiency.
This evaluation board is ideal for developers working on energy harvesting, low quiescent current applications without a standby switcher, and a variety of portable and wearable electronic devices. Typical uses include smoke detectors and thermostats where power efficiency and battery life are critical.
Constant ON-Time control with ultra-low power (ULP) mode for efficient operation. 180nA quiescent current minimizes energy consumption during standby. Output current capability up to 500mA supports a range of load requirements.
Nine selectable output voltages from 1.2V to 3.3V via VSEL pins. Discharge function on VOUT enhances safety and performance. 100% ON mode operation for low input voltage conditions improves energy efficiency. Manufactured in the United States guaranteeing high-quality standards.
This evaluation board is a valuable tool for power management development in industrial, laboratory, and commercial electronics fields, including energy harvesting systems, portable electronics, and HVAC controls.
