PLANO, TX: Diodes Incorporated, manufacturer and supplier of high-quality application specific standard products, has come up with AP65355, and AP65455for high DC output accuracy. The devices are adaptive and constant on-time (COT) mode synchronous buck converters- converters for voltage step down and current step up.  

The newly launched devices regulate low-voltage with high efficiency and provide high DC output accuracy at continuous output currents of 3A and 4A, respectively. Basic applications of the devices include consumer electronics like, TVs and computer monitors, and “green” electronics. Their adaptive on-time control feature helps in maintaining seamless transition between continuous conduction mode (CCM) under higher loads and discontinuous conduction mode (DCM) for lighter loads. They also help in power loss by providing integrated high and low side switches with low RDS (ON).

The other important features of the devices include under-voltage lockout, over-current and over-temperature protection that prevent damage to downstream components and premature component failures.
