The LT3048EDC-15 is a synchronous, high efficiency, dual output voltage regulator for applications where multiple volts are required for proper functioning, such as in computer motherboards, network switches, and routers. This PMIC provides up to 1 Agilent of adjustable output currents (where VCCin is 3.3Vdc or 5Vdc rated) and is powered from any voltage source from 1.8 Vdc to 18Vdc on the input side. Its high efficiency and superior thermal performance, along with its flexible optimization through the addition of external components, makes the LT3048EDC-15 an excellent choice for a variety of applications, such as Point-of-load (POL) converters, power conditioning modules, and automotive, medical, and industrial equipment.

The LT3048EDC-15 uses a buck-boost architecture to provide two independently adjustable voltages. It has a P-channel MOSFET at its output (as opposed to the PNP transistors in the typical buck-boost topology) and an integrated oscillator and control circuitry to enable a compact solution. The P-channel MOSFET follows the polarity of the input voltage and will automatically switch between buck and boost mode depending on the applied voltage. This type of topology does not require a ground reference in order for it to work, as this is already accounted for by the integration of the P-channel MOSFET.

The LT3048EDC-15 can be used in anything from laptops and mobile phones to gaming consoles and home appliances. It is an ideal solution for applications which require multiple output voltages in one small package. Its high efficiency and superior thermal performance makes it perfect for applications in low-power systems and other products where thermal design constraints are more stringent.

The LT3048EDC-15 shares some of the same common features of a traditional buck-boost voltage regulator. Its synchronous buck-boost architecture allows it to adjust its output voltage to match the input voltage, and the adjustable output current allows it to be modified to meet the specific needs of a given application. Additionally, its onboard oscillator, integrated MOSFETs, low component count and small package size allow for a more cost effective and simpler installation.

The LT3048EDC-15 also includes advanced features such as short-circuit protection and adjustable soft start. The short-circuit protection limits the output current to a safe level, protecting both the regulator and the circuits it is powering from damage related to short circuits or other overload conditions. The adjustable soft start helps to limit the inrush current that occurs at startup, and also allows for custom startup ramps for applications in which a slow progression of current is desirable.

In summary, the LT3048EDC-15 provides a high efficiency, dual output voltage regulator ideal for applications which require multiple output voltages and require it all in a small package. Its P-channel MOSFET buck-boost architecture and adjustable offs allows it to be used in a variety of scenarios, while the onboard safety features provide necessary protection from short-circuit and over-current conditions. The LT3048EDC-15 is the ideal choice for products where thermal design constraints are more stringent or for applications which require a more cost effective and simpler installation.
