48V synchronous buck regulators are ‘industry’s first’
Texas Instruments has introduced three new 48V synchronous buck regulators with integrated high side and low side mosfets for single and multiple output power supplies.
The 650mA LM25017, 300mA LM25018 and 100mA LM25019 Fly-Buck converters feature constant on time control architecture, which the company says reduces board space by up to 40% when compared with traditional designs that require multiple dc/dc converters.
In addition, the devices are designed to enable non-isolated voltage regulators and multi-output solutions from input voltages as high as 48V. Each Fly-Buck converter can be configured to provide positive and negative voltage rails, or isolated multiple outputs.
