AS2214  
Primary Side PWM Controller  
Fea tures  
Descrip tion  
Low Startup Current  
The AS2214 is a full featured, pulse width modulation  
controller. Based on an improved AS3842, the AS2214  
provides additional features that reduce component count  
and improve specifications in a wide range of power supply  
designs. The added functionality includes AC power and  
bulkvoltagesensing,over-voltageinput,aswellastheability  
to latch off or bounce through different fault conditions.  
Bulk and AC sensing  
Soft Start  
Single-start or auto-restart  
modes  
Oscillator trimmed for precision  
duty cycle clamp  
The PWM function is controlled by the current sense com-  
parator for normal current mode control and a second  
comparator for voltage mode soft start. A buffered RAMP  
signal is available for slope compensation without loading  
the oscillator. The output stage is a high current totem pole  
output that sees only 85 ns delay from the PWM comparator.  
Standard temperature range  
extended to 105°C  
Remote on / off control  
Buffered Ramp for slope  
compensation  
The AS2214 requires less than 10µA of startup current. The  
undervoltagelockout(UVLO)thresholdsarenominally13.8V  
for turn on and 8 V for turn off. A precision 2.5 V bandgap  
reference serves as an input for the error amplifier. The  
oscillator discharge current is trimmed to provide guaran-  
teed duty cycle clamping.
