Features Integrated 75 volt N-Channel MOSFET Ultra-wide input voltage range from 3.1V to 75V Integrated high voltage bias regulator Adjustable output voltage 1.5% output voltage accuracy Current mode control with selectable compensation Wide bandwidth error amplifier Integrated current sensing and limiting Integrated slope compensation 85% maximum duty cycle limit Single resistor oscillator programming Oscillator synchronization capability Enable / Undervoltage Lockout (UVLO) pin Thermal shutdown Description The LM5002 high voltage switch mode regulator features all of the functions necessary to implement efficient high voltage Boost, Flyback, SEPIC and Forward converters, using few external components. This easy to use regulator integrates a 75 Volt N-Channel MOSFET with a 0.5 Amp peak current limit. Current mode control provides inherently simple loop compensation and line-voltage feed-forward for superior rejection of input transients. The switching frequency is set with a single resistor and is programmable up to 1.5MHz. The oscillator can also be synchronized to an external clock. Additional protection features include: current limit, thermal shutdown, under-voltage lockout and remote shutdown capability. The device is available in both SO-8 and LLP-8 packages.

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.
