SANYO Semiconductor Co., Ltd. has developed low power consumption and high efficiency power supply ICs "Diode Rectifier Type DC-DC Down Converter IC series" that significantly improved power conversion efficiency at light load. Sample shipment is expected to start in June 2010.
Two types are available which are "Controller Type" with external PchFET and "PchFET Built-in Type" with PchFET incorporated in the IC that contributes to reducing the number of parts and the board space. Each type has lineup of products with 45V/36V/22V power resistance. This eco-friendly product can be used in various electronic devices such as OA equipment, AV equipment and game machines.
Product Main Features
- Achieves power conversion efficiency of 80% at the output current of 2mA, which is 3.2 times higher*1 as compared to existing products.
- Achieves current consumption of 80uA during operation (LV5061V). Current consumption at the output current of 1mA reduced by approx. 80%*2.
- Product lineup consists of six types for various applications.
*1 Comparison between LV5061V and our existing products (25% at 2mA), when VIN=12V and VO=5V.
*2 Comparison between LV5061V and our existing products, when VIN=12V and VO=5V.
Summary
For CO2 reduction, electronic equipment at home or office is required to be power saving and one of the key things is reducing the power consumption at light load such as the standby mode. Parts or ICs incorporated in electronic equipment are therefore required to be power saving and highly efficient at light load.
Power supply ICs including DC-DC converter ICs have become indispensable for electronic products. However, conventional DC-DC converter ICs needed to be improved due to inefficiency at light load. To solve this problem, by reducing the circuit current as much as possible, SANYO Semiconductor has developed highly efficient "Diode Rectifier Type DC-DC Down Converter ICs".
Product Main Features
- Achieves power conversion efficiency of 80% at the output current of 2mA, which is 3.2 times higher as compared to existing products.
This product realized high efficiency at light load by reducing the power consumption at output current of 1 to 50mA. Efficiency at 2mA is approx. 80%, which is 3.2 times higher as compared to existing products (25% at 2mA). - Achieves the current consumption of 80uA during operation (LV5061V). Current consumption at the output current of 1mA reduced by approx. 80%.
This product realized the current consumption of 80uA during operation by reducing the circuit current as much as possible. Current consumption at the output current of 1mA was reduced by approx. 80% compared to our existing products. - The product lineup consists of six types for various applications.
To meet customers' diverse needs, "Controller Type" with external PchFET and "Built-in Type" that incorporates PchFET are available and each type has lineup of products with 45V/36V/22V power resistance.
