ONSEMI NCP1230D165R2G PWM Controller
The NCP1230 is a high-performance PWM controller designed for low standby power in medium-to-high power switch-mode power supplies. It features current-mode operation, internal ramp compensation, a lossless high-voltage startup circuit, and cycle skipping at light loads to reduce no-load power consumption. Key protections include latched overload and overvoltage protections, internal soft-start, frequency jittering for EMI reduction, and an event management scheme to disable PFC during standby. Suitable applications include notebook adapters, battery chargers, set-top boxes, TVs, and monitors, providing efficiency and reliable operation in compact packages.
