onsemi NCV1077 High-Voltage Switching Regulators integrate a fixed frequency current mode controller with a 670V MOSFET with an RDS(ON) of 4.7Ω. These switching regulators are available in a PDIP-7 or SOT-223 package. The NCV1077 regulators provide a high level of integration, encompassing soft-start, frequency-jittering, short-circuit-protection, skip-cycle-functionality, a maximum peak current set point, ramp-compensation, and Dynamic-Self-Supply (DSS). These switching regulators feature a 300µA no-load power consumption and 800mA peak current.
The NCV1077 regulators find application in EV auxiliary power supplies and are commonly integrated into end products such as onboard chargers and EV traction inverters. These switching regulators are AEC-qualified, ensuring reliability and performance in automotive applications. The NCV1077 regulators are Pb-free, halogen-free/BFR-free, and RoHS-compliant.
