Overview: Customer Specific Device from ON Semiconductor DAP018A/B/C/D/F PWM Current-Mode Controller for High-Power Universal Off-Line Supplies
• Auto−recovery internal output short−circuit protection • • • • • • • •
for A, B, C and D versions. F is latched Adjustable Timer for Improved Short−circuit Protection OTP and OVP Inputs for Improved Robustness +500 mA / −800 mA Peak Current Capability Up to 28 V VCC Operation Improved Creepage Distance between High−voltage and Adjacent Pin Extremely Low No−load Standby Power This is a Pb−Free Device This Device uses Halogen−Free Molding pound Housed in a SO−14 package, the DAP018X represents an enhanced version of the currently available Speedking controller, the DAP011. With an internal structure operating at a fixed 65 kHz or 100 kHz frequency, the controller directly connects to the high−voltage rail for a lossless and clean startup sequence. Current−mode control also provides an excellent input audio−susceptibility and inherent pulse−by−pulse control. Internal ramp pensation easily prevents sub−harmonic oscillations from taking place in continuous conduction mode designs.
