HIP2100EVAL2 [RENESAS]

The HIP2100 driver IC simplifies driving two MOSFETs in a half-bridge configuration, serving as a low-cost alternative to pulse transformers. It integrates a 115V bootstrap diode, two independent 2A output stages, and control logic in an 8-pin SOIC. Key features include 20ns propagation delay for >1MHz switching, self-correcting logic to prevent latching errors, and UVLO on both bias supplies. The referenced 50W converter design uses a two-switch forward topology with primary-referenced current-mode control, achieving 83% full-load efficiency and 11W/in³ power density at 500kHz. The design emphasizes thermal management, transformer optimization, and loop stability.
