General Description
The LM5022 is a high voltage low-side N-channel MOSFET controller ideal for use in boost and SEPIC regulators. It contains
all of the features needed to implement single ended primary topologies. Output voltage regulation is based on current-mode
control, which eases the design of loop compensation while providing inherent input voltage feed-forward. The LM5022 includes
a start-up regulator that operates over a wide input range of 6V to 60V. The PWM controller is designed for high speed capability
including an oscillator frequency range up to 2 MHz and total propagation delays less than 100 ns. Additional features include
an error amplifier, precision reference, line under-voltage lockout, cycle-by-cycle current limit, slope compensation, soft-start,
external synchronization capability and thermal shutdown. The LM5022 is available in the MSOP-10 package.

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.
