onsemi AC DC Converters, Offline Switches NCV1075P100G

The NCV1075P100G is an automotive high-voltage switcher designed for low power switch-mode power supplies (SMPS). It integrates a fixed frequency current mode controller with a built-in 670 V MOSFET, offering a maximum peak current of 450 mA. The device operates at a frequency of 100 kHz and features soft-start, frequency jittering, and skip-cycle operation to enhance efficiency at light loads. Protection mechanisms include auto-recovery output short circuit protection, overvoltage protection, and a timer for overload detection. The dynamic self-supply feature eliminates the need for an auxiliary winding, allowing for reduced standby consumption below 50 mW. The NCV1075P100G is AEC-Q100 qualified, making it suitable for automotive applications. It is available in a PDIP-7 package and is RoHS compliant. This product is ideal for auxiliary and standby isolated power supplies in hybrid and electric vehicles.
