San Jose, Calif.Power Integrations has announced the TOPSwitch-HX AC-DC power conversion chip, which incorporates a 700-V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device.
TOPSwitch-HX enables power supply designs that easily meet proposed and existing energy standards such as CEC and ENERGY STAR, while delivering up to 48-W without the need for heat-sinking and up to 150-W with a heat sink.
A multi-mode control scheme provides highly efficient operation across the entire load range, eliminating the need for a separate standby power supply (PSU) in A/V products and appliances.
The control algorithm seamlessly transitions between different operating modes to optimize energy efficiency at all power levels, with the capability to deliver more than 600-mW output for 1-watt input and a no-load power consumption of less than 200-mW.
Pricing: In 1000-piece quantities for the TOP258PN, a 35-W part in a DIP-8 package, is $1.57 each.
Availability: Production quantities of TOP254-258 are available now in the following package types: DIP-8, SMD-8, TO-220, SDIP-10.
