Power design accelerator kits

4 June 2003 Power Electronics / Power Management

Power Integrations has introduced two design accelerator kits that it claims enable power supply engineers to quickly and easily create production-worthy designs using its highest performance family of integrated AC-DC switcher ICs, TOPSwitch-GX.

DAK-33 is a highly efficient 45 W (12 V, 3,75 A) design created specifically for LCD monitor power supply applications. The design features 90 V a.c. to 265 V a.c. input operation, with over 79% full-load efficiency. It additionally meets less than 300 mW no-load power consumption and under 1 W standby.

DAK-34 is the company's new general-purpose TOPSwitch-GX DAK, replacing DAK-11. The universal input, 12 V at 30 W output flyback design demonstrates the many advanced features of PI's high-voltage IC family, including under-voltage lockout, overvoltage and hysteretic thermal shutdown, auto-restart, soft-start, adjustable current limit, and the company's EcoSmart energy efficiency technology. It uses only 21 primary-side components.
