Features included are, startup regulator, dual mode current limit, dual alternating gate drivers, thermal shutdown, softstart and slope compensation. This high speed IC has total propagation delays <100nS.

LM5030 www.ti.com SNVS215C – APRIL 2003 – REVISED MARCH 2013 The LM5030 CS and PWM comparators are very fast, and as such will respond to short duration noise pulses. Layout considerations are critical for the current sense filter and sense resistor. The capacitor associated with the CS filter must be placed very close to the device and connected directly to the pins of the IC (CS and RTN).

LM5030 SNVS215C – APRIL 2003 – REVISED MARCH 2013 www.ti.com OUT1, OUT2 and Time Delay The LM5030 provides two alternating outputs, OUT1 and OUT2. The internal gate drivers can each sink 1.5A peak each. The maximum duty cycle for each output is inherently limited to less than 50%. The typical deadtime between the falling edge of one gate driver output and the rising edge of the other gate driver output is 135ns.
