DC/DC LED驱动器
EMD3001-50VC06GRR
Two times charge pump and constant switching frequency configuration with low noise characteristics, low external components makes the EMD3001 unique performance and perfect for the portable applications. Fixed regulated output voltage (EMD3001) is available for different applications with input voltage range from 2.7V to 4.5V and provide up to 100mA of output current.
Soft-start circuitry, preventing the inrush current, thermal shutdown and short circuit protection are all built-in as well. It also features with <1uA low showdown current when the device is disable.
The EMD3001 is available in a 6-pin SOT-26 and TDFN-2x2-6 package (fixed 5V output).
