Realizing Low Power Consumption (100mW max) at No Load
ICs for Switching Mode Power Supplies (SMPS)
= Optimum for auxiliary power supplies at standby condition for equipment =
|Sanken Electric has developed the STR-A6200 Series ICs for small-capacity SMPS. The power consumption of the ICs is less 100 mW at 264 VAC input under no load condition.
The ICs will be launched in March CY05 starting with 1,000k pcs/month, then ramping up to 2,000k pcs/month in April. (Sample price: 180 Yen)
|1.||Development Background and Product Overview|
|With the recent increase of remote controlled equipment such as TV and DVD, and the spread of cell phones and other electronic mobile equipment, the demand is growing for power supplies and adapters of low standby-power consumptions. To meet this, reducing the power consumption in power supply parts at standby condition is the key issue. Reducing discrete part count is also required for downsizing and lower price of equipment
Thus, Sanken Electric has developed the SMPS purpose-built STR-A6200 Series ICs with an built-in Auto Burst Standby Function for less 100 mW power consumption at 264VAC under no load. In addition, the audible noise of transformer is reduced at light load and the combination of Pulse Width Modulation (PWM) system and Frequency Jitter Operation realizes lower EMI compared with our existing products.
The STR-A6200 Series is the optimum IC for SMPS ranging 5 to 25 W, such as standby power supplies for AV and OA equipment, auxiliary power supplies for DVD/CD players or white goods, as well as adapters for cell phones, digital cameras and game machines.
The STR-A6200 Series has versatile built-in protection circuits such as overcurrent, overvoltage, overload, and overheat. Additionally, this IC contributes to the downsizings and cost savings in power supply system because the IC itself is downsized and space saving, and realizes the reduction of discrete-part count for the power supply system by employing DIP8 package and a built-in start-up circuit, and also by having the anti-EMI filter simplified (i.e. cost-saving) due to the low EMI of the IC itself.
