PSS controller boosts power supply efficiency |
21/07/2010
|
| An addition to CamSemi's C2160 family of primary side sensing (PSS) controllers is said to allow manufacturers of higher power embedded and multiple output power supplies to exploit the cost benefits of bipolar transistors.
The C2163 is aimed at universal input adapters and chargers rated at more than 8W. It delivers low standby power consumption and high efficiency power supplies in applications such as networking products and set-top boxes, but is also suited for tablet computer and power tool chargers. |

LDOs are 2% accurate over industrial temperature range |
08/07/2010
|
| A pair of low dropout linear regulators from Diodes Inc accept inputs ranging from 2V to 6V. Both parts are said to be capable of delivering an output voltage adjustable between 0.8V and 5V and fixed voltages of 0.8V, 1V, 1.2V, 1.5V, 1.8V, 2V, 2.5V, 2.8V, 3V, 3.3V and 3.9V. A quiescent current of 35µA means the devices can offer power saving benefits in low power and battery operated products. Both parts are said to be accurate to within 2% over temperatures ranging from -40 to 85°C. |
