KA3842A datasheet

Obsolete as of 14-Sep-2013

Description

The KA3842A / KA3842AC / KA3842AE are fixed PWM controller for Off Line and DC to DC converter applications. The internal circuits include UVLO, low start up current circuit, temperature compensated reference, high gain error amplifier, current sensing comparator, and high current totem pole output for driving a POWER MOSFET. Also KA3842AC / KA3842AE provides low start up current below 0.3mA and short shutdown delay time typ. 100ns. The KA3842AC / KA3842AE has UVLO threshold of 16V(on) and 10V(off). The KA3842AC/KA3842AE can operate within 100% duty cycle.

UAA2016D datasheet

 

Description

The UAA2016D is designed to drive triacs with the Zero Voltage technique which allows RFI−free power regulation of resistive loads. Operating directly on the AC power line, its main application is the precision regulation of electrical heating systems such as panel heaters or irons.

Features

• Zero Voltage Switch for Triacs, up to 2.0 kW (MAC212A8)
• Direct AC Line Operation
• Proportional Regulation of Temperature over a 1°C Band
• Programmable Temperature Reduction
• Preset Temperature (i.e. Defrost)
• Sensor Failsafe
• Adjustable Hysteresis
• Low External Component Count
• Pb−Free Packages are Available
