Categories: DC DC Switching Regulators
Quality Control: Learn More
The onsemi FAN21SV04EMPX is a TinyBuck® series adjustable output voltage buck switching regulator. This device efficiently converts input voltages from 3V to 24V down to a selectable output voltage as low as 0.8V, with a maximum output capability of 4A. Featuring an integrated synchronous rectifier, it optimizes power conversion efficiency. The internal switching frequency can be set between 200kHz and 600kHz, allowing for a balance between component size and efficiency. The FAN21SV04EMPX is housed in a 25-MLP (6x5) package with an exposed pad for enhanced thermal performance, suitable for surface mounting. It operates across a wide temperature range of -40°C to 85°C. This component is widely deployed in industrial automation, consumer electronics, and telecommunications power management applications.
