National Semiconductor LM5035 PWM Controller Datasheet
The LM5035 half‑bridge controller/gate driver integrates high‑side and low‑side drivers capable of 2 A peak current and a supply voltage rating up to 105 V. It includes a programmable resistor‑set oscillator that can run to 2 MHz and can be synchronized to an external clock. The device provides line‑feed‑forward voltage mode control, UVLO, OVP, soft‑start, thermal shutdown and dual‑mode over‑current protection.
The datasheet details pin functions, absolute maximum ratings, electrical characteristics, thermal specifications, typical performance curves, package dimensions and example application circuits. It also contains regulatory and life‑support usage notes from National Semiconductor.
