No, the minimum input voltage is 7.0V. For 5V input applications, look for a lower-voltage buck converter.
Always refer to the official manufacturer datasheet from ROHM for final design validation and the most current product status information.

Word moved through the kinds of people who don’t let words stay where they were meant to be—mechanics, med-techs, a late-night backchannel of hobbyists who fixed things because broken things needed company. Offers followed. People came with devices and stories. A photographer with a camera that produced only black frames. A musician whose vintage synth hummed but never sang. A mother whose baby monitor recorded silence but for a soft, distant lullaby.

The BD9E102FJ integrates both the high-side and low-side power MOSFETs internally. This eliminates the need for an external Schottky diode, reduces component count, and improves overall efficiency by minimizing conduction losses. The low on-resistance of the internal MOSFETs (250mΩ high-side, 200mΩ low-side) ensures minimal heat generation even at the full 1A load.
The BD9E102FJ is a synchronous buck DC/DC converter with integrated power MOSFETs, designed to be both efficient and space-saving. 7.0V to 26V. Output Current: Maximum 1.0A. Switching Frequency: Fixed at 570 kHz (Typ.). Efficiency: Up to 89.6% at 0.7A load. Package: SOP-J8 (Small Outline Package). Adjustable Output: Can be set from 1.0V up to Pinout Configuration

A basic BD9E102FJ application requires the following external components:
A standout feature highlighted in the ROHM BD9E102FJ Technical Documentation is its proprietary SLLM™ control scheme. While standard buck regulators suffer from severe efficiency drops when load currents fall, SLLM™ automatically transitions the IC into an energy-saving mode during light loads. It maintains a high efficiency of approximately 80% even at a minuscule output current of 2. Current Mode Control Architecture
9e102 answered in increments. Not with speech, not with data, but with glimpses—short bursts of pattern and scent, of light folded through a prism and the taste of copper. When she probed its surface, the ceramic yielded stories like seams: a hospital corridor where a boy learned to count by the rhythm of the ventilator; a tundra under a green aurora where a woman cataloged the color of cold; a small boat at dawn where a father taught his child to fix a broken compass. These were not its own memories. They felt borrowed, stitched from the loose ends of others’ lives. Each was connected to someone who had held 9e102 in passing, someone who had trusted their secrets to this small thing.

A primary highlight of this regulator is ROHM's proprietary control mechanism. When an application drops into a low-power or standby state, the IC automatically scales down its switching activity, sustaining up to 80% efficiency even at a minimal 10mA output current . Key Specifications
