Maxim recently introduced the MAX5003 high-voltage switched-mode power controller that can be used to design isolated or non-isolated power supplies with multiple voltage outputs and includes a high-voltage start-up circuit internally with a wide operating voltage range of 11V ~ 110V. The MAX5003 can drive an external N-channel power MOSFET with the chip’s current limit
