MAX5042/MAX5043 EVALUATION KIT AVAILABLE Two-Switch Power ICs with Integrated Power MOSFETs and Hot-Swap Controller General Description The MAX5042/MAX5043 isolated multimode PWM power ICs feature integrated switching power MOSFETs connected in a voltage-clamped, two-transistor, power-circuit configuration. These devices operate from a wide 20V to 76V input voltage range. The MAX5042 includes a hotswap controller for use with an external power MOSFET to limit inrush current for applications where the power supply is plugged into a live power backplane. The MAX5043 does not include a hot-swap controller. The voltage-clamped power topology of the MAX5042/ MAX5043 enables full recovery of stored magnetizing and leakage inductive energy for enhanced efficiency and reliability.
