Preliminary
EMD3001
Low Noise, Regulated Charge Pump DC/DC
Converter
General Description
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.
Applications
White LED Driver
3V to 5V Charge Pump Conversion
Battery Backup Supplies
Handheld Portable Devices
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 package (fixed
5V output).
Features
Low Noise Constant Frequency Operation (2MHz)
100mA Output Current
Power Range form 2.7V to 4.5V
Shutdown Current < 1µA
Needs No Inductors
Soft Start Function Reduces Inrush Current And Has
Slew Rate Control
Output Voltage Regulates to 5V ± 4% or Adj.
Uses Small Ceramic Capacitor of 1µF
Thermal Shutdown Protects Output Over Loading
Protects Output Shorted to Ground
PWM dimming Control WLED Brightness
5V Fixed Version in SOT-26
