Notebook Adapter Demonstration Evaluation Board

The NCP1236 is a new fixed-frequency current-mode controller featuring Dynamic Self-Supply (DSS). This device is pin-to-pin compatible with the previous NCP12xx families. The DSS function greatly simplifies the design of the auxiliary supply and the VCC capacitor by activating the internal startup current source to supply the controller during transients. Due to frequency foldback, the controller exhibits excellent efficiency in light load condition while still achieving very low standby power consumption.

Fixed-Frequency Current-Mode Operation with Built-In Ramp Compensation
65 kHz or 100 kHz Oscillator Frequency
Frequency Foldback then Skip Mode for Maximized Performance in Light Load and Standby Conditions
VCC Operation up to 28 V, with Overvoltage Detection
