AS2214 - ASTEC

AS2214 Primary Side PWM Controller

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 bo.

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.
