NCP1238AD65R2G More Descriptions
Current Mode PWM Controller -0.3V to 20V 800mA 65kHz 7-Pin SOIC T/R
PWM Controller Fixed Freq. Latched SOIC7 | ON Semiconductor NCP1238AD65R2G
The NCP1238 is a new generation of the NCP12xx fixed-frequency current-mode controllers featuring Dynamic Self-Supply (DSS) pin to pin compatible with the previous generation. The DSS function greatly simplifies the design of the auxiliary supply and the VCC capacitor by activating the internal start-up current source to supply the controller during transients. Due to its proprietary Soft-Skip mode combined with frequency foldback the controller exhibits excellent efficiency in light load condition while still achieving very low standby power consumption. This Soft-Skip feature also dramatically reduces the risk of acoustic noise which enables the use of inexpensive transformers and capacitors in the clamping network. Internal frequency jittering ramp compensation and a versatile latch input make this controller an excellent candidate for converters where ruggedness and components cost are the key constraints. In addition the controller includes a new high voltage circuitry that combines a startup current source and a brown-out / line OVP detector able to sense the input voltage either from the rectified ac line or the dc filtered bulk voltage. Finally due to a careful design the precision of critical parameters is well controlled over the entire temperature range (-40C to 125C) enabling easier design and increased safety (e.g. 5% for the peak current limit 7% for the oscillator).
