**The NCP1234 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.
Features
Fixed−Frequency Current−Mode Operation with Built−In Ramp Compensation
65 kHz or 100 kHz Oscillator Frequency version
Frequency Foldback then Skip Mode for Maximized Performance in Light Load and
Standby Conditions
Timer−Based Overload Protection with Latched (option A) or Auto−Recovery
(option B) Operation
High−voltage Current Source with Dynamic Self−Supply, Simplifying the Design
of the VCC Capacitor
Frequency Modulation for Softened EMI Signature, including during Frequency
Foldback mode
Adjustable Overpower Compensation
Latch−off Input for Severe Fault Conditions, Allowing Direct Connection of an
NTC for Overtemperature Protection (OTP)
VCC Operation up to 28 V, with Overvoltage Detection
±500 mA Peak Source/Sink Current Drive Capability
4.0 ms Soft−Start
Internal Thermal Shutdown
Pin−to−Pin Compatible with the Existing NCP12xx Series
