ON Semiconductor Introduces Fixed-Frequency Current-Mode Controller for High Efficiency, Compact Adapter SolutionsControllers Offer High Efficiency and Low Standby Power Consumption in Wide Range of AC-DC Adaptor Applications
The Dynamic Self−Supply (DSS) function of the NCP1237 and NCP1238 provide an integrated start-up current source that intelligently handles start-up and line transient events. This simplifies the design of the auxiliary supply, reducing the size of the VCC capacitor. To minimize external component count, the controllers integrate brown-out, over-power compensation and ramp compensation, allowing a compact solution to be designed. The new fixed-frequency, current-mode controller ICs have an operational temperature range of −40 °C to +125 °C and are offered in a compact SOIC-7 package. “With utility bills continuing to increase and concerns about the environment growing, it is vital to use electrical power at the greatest possible rates of efficiency,” said Christophe Warin, AC-DC business unit manager at ON Semiconductor. “The NCP1237, NCP1238 and NCP1288 are highly integrated solutions that will allow engineers to develop power system designs that maintain strong reliability, have a low bill-of-materials and do not waste energy when the product is in standby mode.” The NCP1237 controller will be featured in a live demo at the ON Semiconductor booth (#315) during APEC, which takes place Feb. 22-25, 2010 in Palm Springs, Calif.
