 Description:
The LM26480 is a multi-functional Power Management Unit, optimized for low-power digital applications. This device integrates two highly efficient 1.5A step-down DC/DC converters and two 300mA linear regulators. The LM26480 is offered in a tiny 4 x 4 x 0.8mm LLP-24 pin package.
The LM26480 Evaluation Kit requires the assembly of the user-specified feedback network. Pads are provided on the board to
solder down surface mount resistors and capacitors. The LM26480 Evaluation Kit allows the user to effectively utilize all of the
functions of the LM26480.
Features:
- Compatible with advanced applications processors and FPGAs
- 2 LDOs for powering Internal processor functions and I/Os
- Precision internal reference
- Thermal overload protection
- Current overload protection
- 24-lead 4 x 4 0.8mm LLP package
- External Power-On-Reset function for Buck1 and Buck2
- Undervoltage lock-out detector to monitor input supply voltage

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.
