The DAP018B features an efficient protective circuitry which, in presence of an overcurrent condition, disables the output pulses while the device enters a safe burst mode, trying to re−start. Once the fault has gone, the device auto−recovers. By implementing a timer to acknowledge a fault condition, independently from the auxiliary supply, the designer’s task is eased when stringent fault mode conditions need to be met.

A dedicated input helps triggering a latch−off circuitry which permanently disables output pulses, for instance to implement an over voltage protection (OVP). A separate input accepts a direct NTC connection to ground for a simple and efficient over temperature protection (OTP).


• Fixed−frequency 65 kHz (A and B versions) or 100 kHz (C and D versions) Current−mode Control Operation
• Internal and Adjustable Over Power Protection (OPP) Circuit
• Frequency Foldback down to 25 kHz and Skip−cycle in Light Load Conditions
• Reduced Internal Bias Currents for Improved Standby Performance
