EONE-2501S is an isolated power management IC with current control mode that adapts to global input voltage. It complies with the "1 Watt Initiative" standard proposed by the International Energy Agency (IEA), reducing standby power consumption to less than 0.1W (110VAC)-0.3W (220VAC). The product adopts SOIC?8 package, with a driving capacity of more than 1A, and can directly drive almost any MOSFET without an external driver. The product is used in isolated AC?DC adapters, battery chargers or standby power supplies and isolated power supplies below 200W. The product adopts one-by-one current pulse control to ensure product safety. Automatically adjust the current limit amplitude to adapt to changes in input voltage.
After the output power drops to 30% of the full power, the switching frequency is automatically reduced to 10KHZ to reduce switching losses to meet the requirements of reducing no-load and light-load losses.
Due to the use of zero voltage and zero current switching technology, the typical efficiency reaches 89% at 12V output 1A, leading the industry.
No additional measures are required when the output is short-circuited, and the output voltage is automatically reduced to ensure product safety. The output is automatically restored after the short-circuit fault is eliminated.
