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 in-
herent 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. Addi-
tional 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.
