Issue Number 001 May 2016 New Product Announcement AP3983B/C/D/E/R High-Performance Primary-Side Power Switcher for Off-Line SMPS The AP3983B/C/D/E/R is a family of enhanced- performance power switchers delivering improved: Conversion efficiency Voltage & current accuracy Protection functions The family regulates the output voltage and current on the primary side by piece- wise Pulse Frequency Modulation (p-PFM) in discontinuous conduction mode with an operating The Diodes Advantage frequency up to 80kHz. The AP3983B/C/D/E/R family Accurate Primary Side Regulation Eliminates Opto-coupler and 431/CC-CV components, reducing has built-in fixed cable voltage overall BOM size and cost compensation. Typical applications include chargers, Built-in MOSFET: 650 BV for AP3983B/C/D Data-comms adapters and DSS 700 BV for AP3983E/R DSS home appliance power Reduces solution size High-drain voltage meets wide AC input supplies. Internal Output Cable Voltage Drop Compensation The AP3983B/C/R are Reduces external components and solution size packaged in SO-7, delivering Switching Frequency Dithering Function output powers up to 10W and Improves EMC performance the AP3983C/D/E are Multi-Interval Pulse Frequency Modulation packaged in PDIP-7, Avoids audible noise delivering powers up to 20W.
