DESCRIPTION
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 feedforward.
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 VSSOP-
10 and WSON-10 packages.
