Description
General part information
LM5020 Series
The LM5020 high voltage pulse-width-modulation (PWM) controller contains all of the features needed to implement single ended primary power converter topologies. Output voltage regulation is based on current-mode control, which eases the design of loop compensation while providing inherent line feed-forward. The LM5020 includes a high-voltage start-up regulator that operates over a wide input range up to 100V. The PWM controller is designed for high speed capability including an oscillator frequency range to 1MHz and total propagation delays less than 100ns. Additional features include an error amplifier, precision reference, line under-voltage lockout, cycle-by-cycle current limit, slope compensation, softstart, oscillator synchronization capability and thermal shutdown. The controller is available in both MSOP-10 and LLP-10 packages.
