AS2214 Primary Side PWM Controller Features • Low Startup Current • Bulk and AC sensing • Soft Start • Single-start or auto-restart modes • Oscillator trimmed for precision duty cycle clamp • Standard temperature range extended to 105°C • Remote on / off control • Buffered Ramp for slope compensation • Standard current mode control Description 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 bulk voltage sensing, over-voltage input, as well as the ability to latch off or bounce through different fault conditions.
