 Diodes Incorporated DIOD, a leading global manufacturer and 
 supplier of high-quality application specific standard products within 
 the broad discrete, logic, analog and mixed-signal semiconductor 
 markets, today introduced the AP3984 high-performance power switcher. 
 With its unique integrated high-voltage (HV) start-up circuit, this 
 device provides a cutting-edge solution for line-powered chargers and 
 adaptors in the consumer and industrial markets. Delivering increased 
 conversion efficiency with better voltage and current accuracy, the 
 AP3984 also features ultra-low power consumption and improved protection 
 functions.
 
 
 Designed as a primary-side controller, the AP3984 realizes excellent 
 transient characteristics when combined with secondary-side ICs such as 
 the AP4341/2, supplying outputs above 4.3V. This is achieved with 
 current and voltage tolerances of just ±5%. The built-in start-up 
 circuit with integrated 700V bipolar junction transistor also eliminates 
 external resistors, simplifying system design and allowing the AP3984 to 
 directly switch the line input. The AP3984 also has a programmable line 
 voltage drop-compensation function.
 
 
 With protection features such as over-voltage, open- and short-circuit 
 protection, and over-temperature protection (OTP) with auto-restart, the 
 AP3984 provides a high-performance, highly integrated and cost-effective 
 solution that also meets Energy Star 6.0 efficiency criteria with a 
 standby power of less than 10mW. Multiple PWM/PFM switching modes 
 combined with a frequency dithering function further aid efficiency 
 while improving EMC performance and reducing audible noise.
 
 
 The AP3984MTR-G1 power switcher is available in the space-saving in SO-7 
 package.
