General Description
The LM5015 high voltage switch mode regulator features all the functions necessary to implement efficient high voltage Two-Switch
Forward and Two-Switch Flyback regulators, using a minimum of external components. This easy to use regulator integrates
high side and low side 75 Volt N-Channel MOSFETs with a minimum 1 Amp peak current limit. The voltage across the MOSFETs
employed in the two-switch topology is clamped to the input voltage, allowing the input voltage range to approach the rating
of the MOSFETs. The regulator control method is based on current mode control providing inherent ease of loop compensation
and line feed-forward for superior rejection of input transients.
The operating frequency is set with a single resistor and is programmable up to 750 kHz. The oscillator can also be synchronized
to an external clock. Additional protection features include cycle-by-cycle current limiting, thermal shutdown, under-voltage
lockout and remote shutdown capability. The device is available in the TSSOP-14EP package featuring an exposed die attach
pad to enhance thermal dissipation.

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.
