| $129.00 each | 1 |
| Description:
The LM26484 is a multi-function, configurable Power Management Unit. This device integrates two highly efficient 2.0A Step-Down DC/DC converters, one LDO Controller, a POR (Power on Reset) circuit, and thermal overload protection circuitry. All regulator output voltages are externally adjustable. The LDO controller is a low-voltage NMOS voltage regulator. The LM26484 is offered in a 5 x 4 x 0.8 mm LLP-24 pin package.
The LM26484 evaluation board is a working demonstration of the two step-down DC-DC converters and an LDO controller. The application note helps the user of the evaluation board make the best use of the LM26484 with their application.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
