Texas Instruments LM5039 Half-Bridge PWM Controller
Texas Instruments LM5039 Half-Bridge PWM Controller with Advanced Current Limit contains all of the features necessary to implement half-bridge topology power converters using voltage mode control with line voltage feed-forward. TI LM5039 PWM controller is a functional variant of the LM5035B half-bridge PWM controller, featuring average current limit during an overload event to balance the center-point of the half-bridge capacitor divider. The floating high-side gate driver is capable of operating with supply voltages up to 105V. Both the high-side and low-side gate drivers are capable of 2A peak. LM5039 evaluation board is designed to provide the design engineer with a fully functional power converter based on the half-bridge topology to evaluate the LM5039 controller.Features
