The LM5035C is a functional variant of the LM5035B halfbridge PWM controller. The amplitude of the SR1 and SR2 waveforms are 5V instead of the Vcc level. Also, the soft-stop function is disabled in the LM5035C. The LM5035, LM5035A, LM5035B, and LM5035C include a floating high-side gate driver, which is capable of operating with supply voltages up to 105V. Both the high-side and lowside gate drivers are capable of 2A peak. An internal high voltage startup regulator is included, along with programmable line undervoltage lockout (UVLO) and overvoltage protection (OVP). The oscillator is programmed with a single resistor to frequencies up to 2MHz. The oscillator can also be synchronized to an external clock. A current sense input and a programmable timer provide cycle-by-cycle current limit and adjustable hiccup mode overload protection. |
