NCP1060: High-Voltage Switcher for low Power offline SMPS

PublishTime：2021-06-22

■ The NCP1060 integrate a fixed frequency current mode controller with a700 V MOSFET. Available in a PDIP-7 and SOIC-10 package, the NCP1060 offer a high level of integration, including soft-start, frequency-jittering, short-circuit protection, skip-cycle, adjustable peak current set point, ramp compensation, and a Dynamic Self-Supply (eliminating the need for an auxiliary winding).Unlike other monolithic solutions, the NCP1060 is quiet by nature: during nominal
■ load operation, the part switches at one of the available frequencies (60 or 100 kHz). When the output power demand diminishes, the IC automatically enters frequency foldback mode
■ and provides excellent efficiency at light loads. When the power demand reduces further, it enters into a skip mode to reduce the standby consumption down to a no load condition. Protection features include: a timer to detect an overload or a short-circuit event, Overvoltage Protection with auto-recovery and AC input line voltage detection (A version).The ON proprietary integrated Over Power Protection (OPP) lets you harness the maximum delivered power without affecting your standby performance simply via external resistors. The NCP1060/NCP1063 family can be seamlessly used both in non-isolated and in isolated topologies.
