TI's flyback controller surpasses Energy Star 5 standby power requirements for 10- to 65-W AC adapters

USA: Expanding its line of energy-efficient, no-load adapter power controllers, Texas Instruments Inc. (TI) announced the industry's first flyback controller that exceeds Energy Star 5 standby power requirements for 10- to 65-W AC/DC adapters used with notebooks, motor control, smart meters, micro-inverters and other high-powered applications.

Used in conjunction with TI's award-winning WEBENCH online design tool, the LM5023 flyback controller simplifies and speeds high-voltage DC/DC designs.

TI's new LM5023 isolated quasi-resonant pulse-width modulation (PWM) controller with integrated 700-mA driver offers high efficiency at up to 90 percent, low EMI and less than 10-mW of standby power. The LM5023 provides 1-percent accurate output voltage regulation, eliminating the need for cable compensation. When coupled with the highly accurate LMV431 shunt reference, it provides a competitively priced, 1-percent accurate flyback controller system.
