General Description

The LM5030 High Voltage PWM controller contains all of the features needed to implement Push-Pull and Bridge topologies, using current-mode control in a small 10 pin package. This device provides two alternating gate driver outputs. The LM5030 includes a high-voltage start-up regulator that operates over a wide input range of 14V to 100V. Additional features include: error amplifier, precision reference, dual mode current limit, slope compensation, softstart, sync capability and thermal shutdown. This high speed IC has total propagation delays less than 100ns and a 1MHz capable single resistor adjustable oscillator.

Package: MSOP-10 and thermally enhanced LLP-10 (4mm x 4mm).

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
