Power Integrations, Inc. announced availability of the PeakSwitch PKS607, an integrated power conversion IC capable of handling peak demand of up to 127 W. The PKS607 addresses a wide range of applications that exhibit very high peak-to-RMS (root mean square) power requirements, such as printers, audio amplifiers, and home entertainment systems. This PeakSwitch® family provides peak power on demand while allowing designers to specify a transformer sized for the continuous power level. This capability significantly reduces the size, weight, and cost of the overall power supply design.
PeakSwitch PKS607 handles almost 50% more peak power than earlier PeakSwitch ICs.
The new device incorporates a 700 V MOSFET and low-voltage control circuitry on a monolithic IC. ON/OFF control ensures highly efficient operation at all load conditions, plus very low standby-power consumption. This enables equipment designers to easily comply with all current energy-efficiency standards, including the proposed ENERGY STAR efficiency standard for printers, which specifies power budgets during standby, sleep and active operation. Other key features include integrated auto-restart, hysteretic thermal shutdown and integrated frequency jittering to minimize EMI.
PKS607 is available in lead-free, plastic through-hole DIP-8 and higher power standard TO-220 packages. Pricing in 1000-piece quantities for the PKS607 - offering 75 W continuous, 127 W peak in an F or Y package - is $1.50. Small quantities are available now from factory stock, with production quantities available six weeks ARO.
