EMD3001-Low Noise,Regulated Charge Pump DC/DC Converter DataSheet
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).
