The NCP1230D100R2G from ON Semiconductor is a fixed-frequency, current-mode PWM controller. It is designed to achieve low standby power in medium-to-high power Switched-Mode Power Supplies (SMPS), making it suitable for applications like notebook adapters and offline battery chargers.
Key features include internal ramp compensation, a high-voltage startup circuit for loss-less startup, and skip-cycle capability at low peak currents to minimize no-load power consumption. The device offers internal 2.5 ms soft-start, internal leading edge blanking, and internal frequency jittering for improved EMI signature. It also includes latched primary overcurrent and overvoltage protection, as well as short-circuit protection independent of the auxiliary level.
This controller operates within a voltage range of 7.7V to 18V with a fixed frequency of 100kHz and supports an 80% duty cycle. It is housed in a compact 8-SOIC package suitable for surface mounting.
The NCP1230 series is ideal for building rugged and efficient power supplies, offering features that contribute to reduced power consumption and enhanced protection.
