General Description
The LM25007 is a monolithic step-down switching regulator featuring all of the functions needed to implement a low cost, efficient,
power supply. Capable of driving a 0.5Amp load over a 9V-42V input voltage range, this device is easy to apply and is provided
in the small MSOP-8 and the thermally enhanced LLP-8 packages. Ultra-fast transient response is achieved through the use
of a constant on-time architecture with Vin feed forward. This feature provides an almost constant operating frequency over
load and input voltage variations. The operating frequency can be adjusted with a single resistor. This architecture is easy
to use and tolerant of component selection. An intelligent current limit is implemented in the LM25007 with forced off time
that is inversely proportional to Vout thus ensuring recovery from fault conditions. The output voltage may be set from 2.5V
to >30V. To improve efficiency in light load applications, the Vcc pin can be connected to an external voltage source to
eliminate the drop through the internal regulator. Additional features include: thermal shutdown, Vcc under-voltage lockout,
gate drive under-voltage lockout, and max duty cycle limiter.

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.
