WINSEMI WS2299

WS2299 is a high performance current mode PWM controller, optimized for low power AC/DC adapter applications. For lower the standby power and higher RoHS compliant, the IC offers a Burst Mode control feature and ultra-low start-up current and operating current, that is, at the condition of no load or light load, WS2299 can reduce the switch frequency linearly which minimize the switching power loss; the ultra-low startup current and operating current make a reliable power for startup design, and also large resistor can be used in the startup circuit to improve switching efficiency. The internal synchronous slope compensation circuit reduces the possible sub-harmonic oscillation at high PWM duty cycle output.
