ON Semiconductor has launched a new one-channel Quad-Mode(TM) LED Driver, the CAT3661.
With a patented architecture and integrates fault protection and fault diagnostics, the CAT3661 is designed to be used in ultra low power LED applications such as portable handheld medical equipment powered by coin cell batteries with a current of up to 5 mA.
The CAT3661 has some features as following:Packaged in a 16-lead TQFN package measures 3 mm x 3 mm x 0.8 mm high. The quad-mode charge pump supports a wide range of input voltages from 2.0 V to 5.5 V and also helps the CAT3661 achieve peak efficiency levels of up to 92 percent - up to 10 percent higher than traditional high efficiency 1.5x tri-mode charge pumps. A typical quiescent current of 150 uA across all operating modes at full load and a zero current shutdown help reduce power consumption and ensure that application battery life is maximized. Pricing for these devices is $0.86 per unit in 10,000 unit quantities.
