Low Noise Bias Generator in 2mm x 2mm DFN
The LT3048-15's internal high efficiency switch and 2.2MHz constant frequency operation delivers a low ripple output to the LDO, delivering 15V with ultralow output ripple and noise of less than 500µVPK-PK. Its current-mode control enables fast transient response without the need for complex external compensation. To further enhance system reliability, the LT3048-15 offers short-circuit and thermal protection as well as load disconnect in shutdown.
The LT3048EDC-15 is available in a 2mm x 2mm DFN-8 package, priced at $1.65 each for 1,000 piece quantities. An industrial temperature (-40°C to 125°C) version, the LT3048IDC-15, is priced at $1.82 each for 1,000 piece quantities. Both versions are available from stock.
