Overview
LM5020 100V Current Mode PWM Controller October 2004 LM5020 100V Current Mode PWM Controller General 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 feed-forward.
The LM5020 includes a highvoltage 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.
