LM5002 High Voltage Switch Mode Regulator

Check for Samples: LM5002

FEATURES

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

SOIC-8 and WSON-8 packages.
