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-V N-Channel MOSFET with a 0.5-A 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 1.5 MHz. The oscillator can also be synchronized to an external clock. Additional protection features include: current limit, thermal shutdown, undervoltage lockout and remote shutdown capability. The device is available in both 8-pin SOIC and 8-pin WSON packages. To create a custom regulator design, use the LM5002 with WEBENCH® Power Designer.
