100V Current Mode PWM Controller
LM5020
100V Current Mode PWM Controller
General DescriptionThe LM5020 high voltage pulse-width-modulation (PWM)
controller containsallof the features neededto implement
single ended primary power converter topologies. Output
voltage regulationis basedon current-mode control, which
eases the designof loop compensation while providingin-
herent line feed-forward. The LM5020 includesa high-
voltage start-up regulator that operates overa wide input
rangeupto 100V. The PWM controlleris designedfor high
speed capability includingan oscillator frequency rangeto
1MHz and total propagation delays less than 100ns. Addi-
tional features includean error amplifier, precision reference,
line under-voltage lockout, cycle-by-cycle current limit, slope
compensation, softstart, oscillator synchronization capability
and thermal shutdown. The controlleris availablein both
MSOP-10 and LLP-10 packages.
Features Internal Start-up Bias Regulator Error Amplifier Precision Voltage Reference Programmable Softstart1A Peak Gate Driver Maximum Duty Cycle Limiting (80%for LM5020-1or
50%for LM5020-2) Programmable Line Under Voltage Lockout (UVLO) with
Adjustable Hysteresis Cycle-by-Cycle Over-Current Protection Slope Compensation (LM5020-1) Programmable Oscillator Frequency with
Synchronization Capability Current Sense Leading Edge Blanking Thermal Shutdown Protection
