LM5030
100V Push-Pull Current Mode PWM Controller
General Description
The LM5030 High Voltage PWM controller contains all of the
features needed to implement Push-Pull and Bridge topolo-
gies, 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 oper-
ates over a wide input range of 14V to 100V. Additional
features include: error amplifier, precision reference, dual
mode current limit, slope compensation, softstart, sync ca-
pability 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).
