• Manufacturer Part Number: ME7660
• Description: Charge Pump DC-DC Voltage Converter
• Manufacturer: Nanjing Micro One Electronics

! The drive circuitry consumes no power.
! The output switches have extremely low ON resistance and no offset when
! The impedances of the pump and reservoir capacitors are negligible at the pump
Notes:
! Supply voltage should not exceed maximum rating;
! Do not connect LV terminal to GND for supply voltages greater than 3.5V;
! Do not short circuit the output to V
! Polarized capacitors should be connected as the figure above.
Typical Application Circuit
1.5V~ -10V while a positive supply from +1.5V ~ +10V is available. When V
the output resistance is about 100 ; The output voltage is –4V while the load current
is 10mA.
