Off-Line PWM Controllers integrate power MOSFET.
Press Release Summary:
January 23, 2014 - Available in DIP-8 and SOIC-8 packages, STR4A100 series incorporates sense MOSFET and current mode PWM controller IC. Products use secondary side regulation topology and make it possible to lower stand-by power to <10 mW. Low standby power is accomplished by automatic switching between PWM operation in normal operation and burst-oscillation under light load conditions. Suitable areas of use include appliance, office automation, consumer, and industrial markets.

Allegro MicroSystems, LLC Introduces New Off-Line PWM Controllers with Integrated Power MOSFET
Press release date: January 1, 2014
This new series uses a secondary side regulation topology suitable for low power SMPS regulators in white goods and other applications. An auxiliary power supply, which is separated from the inverter or main power supply, may require high-efficiency and low stand-by power. The STR4A100 series makes it possible to lower the stand-by power to less than 10 mW. The low standby power is accomplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load conditions. The end result yields a high cost-performance power supply system with few external components.
The STR4A series is available in both DIP-8 and SOIC-8 packages. Pricing for 1,000 pieces is as follows:
STR4A162D - $1.10
STR4A162S - $1.10
STR4A164HD - $1.30
