3.1-75V Wide Vin, 0.5A Current Mode Boost, Flyback, Sepic Converter

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.
