L4981AD
The L4981 I.C. provides the necessary features to achieve a very high power factor up to 0.99. Realized in BCD 60II technology this power factor corrector (PFC) pre-regulator contains all the control functions for designing a high efficiency-mode power supply with sinusoidal line current consumption. The L4981 can be easily used in systems with mains voltages between 85V to 265V without any line switch. This new PFC offers the possibility to work at fixed frequency (L4981A) or modulated frequency (L4981B) optimizing the size of the input filter; both the operating frequency modes working with an average current mode PWM controller, maintaining sinusoidal line current without slope compensation.
Besides power MOSFET gate driver, precise voltage reference (externally available), error amplifier, undervoltage lockout, current sense and the soft start are included. To limit the number of the external components, the device integrates protections as overvoltage and overcurrent. The overcurrent level can be programmed using a simple resistor for L4981A. For a better precision and for L4981B an external divider must be used.

TEA1782T
The TEA1781T and TEA1782T are designed to cooperate with the TEA1771T primary side controller in a unique converter topology based on the active clamp forward converter. On the secondary side the output voltages are regulated via bidirectional switches. A typical application area of this converter is a power supply for a desktop PC.
The TEA1781T and TEA1782T are secondary control ICs and regulate each output voltage independently of the primary duty cycle and other secondary output voltages. Because of these separated regulations, the system does not show any cross regulation and makes the design of the transformer easier. As each output can also be completely turned off, the system allows for an integrated standby supply. To maximize the efficiency in Standby mode, the duty cycle and operating frequency are minimized in Standby mode. The TEA1781T and TEA1782T have integrated drivers and individual output voltage regulators. In this way the 3.3 V, 5 V, 12 V and 5 V standby outputs of a typical PC power supply are regulated separately giving accurate output voltages and fast transient response.
All requirements according to the Intel ATX specification (V 2.0) are integrated, such as soft start, a PS_ON# connection, a PwrOK signal and all required protections like OverCurrent Protection (OCP) and OverVoltage Protection (OVP). These voltage and current levels are monitored at each output separately. The system also has an OverTemperature Protection (OTP) function. The system fulfills the current and proposed efficiency standards such as 80+ gold, energy star and blue angel. The TEA1781T and TEA1782T are implemented in a high voltage (ABCD) Silicon On Insulator (SOI) process.
