Integrated Switcher IC family with Peak Power capability is Industry First

A new family of ICs for power supplies with peak-to-continuous power ratios of up to 3:1, has been introduced by Power Integrations, the leader in high-voltage analog integrated circuits for power conversion.

Power Integrations Switcher IC Power conversion IC complies with energy-efficiency standards
As the industry's first monolithic powerconversion IC with peak-mode operation, PeakSwitch enables highly integrated, energy-efficient power supplies for applications such as printers, personal video recorders (PVRs), audio amplifiers, broadband modems and DC motor drives. It features a 700V MOSFET and low-voltage control circuitry integrated on a monolithic IC.

The device employs ON/OFF control, providing low standby power consumption as well as constant active-mode efficiency. This enables compliance 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 autorestart, hysteretic thermal shutdown, and integrated frequency jittering to minimize EMI. The device is available in lead-free, plastic through-hole DIP-8 packages, and higher power standard TO-220 packages.
