100V Push-Pull Current Mode PWM Controller
LM5030
100V Push-Pull Current Mode PWM Controller
General DescriptionThe LM5030 High Voltage PWM controller containsallofthe
features neededto implement Push-Pull and Bridge topolo-
gies, using current-mode controlina small10pin package.
This device provides two alternating gate driver outputs. The
LM5030 includesa high-voltage start-up regulator that oper-
ates overa wide input rangeof 14Vto 100V. Additional
features include: error amplifier, precision reference, dual
mode current limit, slope compensation, softstart, sync ca-
pability and thermal shutdown. This high speedIC has total
propagation delays less than 100ns anda 1MHz capable
single resistor adjustable oscillator.
Package: MSOP-10 (Contact factoryfor thermally enhanced
LLP availability).
Features Internal High Voltage Start-up Regulator Single Resistor Oscillator Setting Synchronizable Error Amplifier Precision Reference Adjustable Softstart Dual Mode Over-Current Protection Slope Compensation Direct Optocoupler Interface 1.5A Peak Gate Drivers Thermal Shutdown
Applications Telecommunication Power Converters Industrial Power Converters +42V Automotive Systems
