ME7660 Charge Pump DC-DC Voltage Converter
Introduction
Me7660 is a charge pump dc-to-dc voltage converter using AL-gate CMOS
technology and optimization design. It converters a +1.5V to +10V input to a
corresponding -1.5V to -10V output using only two external capacitors, eliminating
inductors and their associated cost, size and EMI. The on-board oscillator operates at
a nominal frequency of 10KHZ. Operation below 10 KHZ (for lower supply current
applications) is possible by connecting an external capacitor from OSC to ground.
Features:
! Converts +5V Logic supply to + 5V
! Wide input voltage range: 1.5V~10V
! Efficient voltage conversion: 99.9%
! Good power efficiency: 98%
! Low power supply: 50uA @5Vin
! Easy to use: only two external capacitors required
! 8-pin DIP and 8-pin small outline packages are available
! Compatible with RS232 negative power supply standard
! High ESD protection: up to 3kV
! No Dx diode needed for high voltage operation
Pin Configuration
Packages: 8-pin DIP and 8-pin SOIC

Combined Negative Voltage Conversion and Positive Supply Multiplication
In the figure, C1 C3 are the pump and reservoir capacitors respectively for the
generation of the negative voltage; C2 C4 are the pump and reservoir capacitors
respectively for the multiplied positive voltage. When +5V supply is provided, +9V
and -5V can be generated.
Positive Voltage Multiplication/Conversion
Since the switches that allow the charge pumping operation are bi-directional, the
charge transfer can be per-formed backwards as easily as forwards. Following figure
shows ME7660 transforming – 5V to +5V (or +5V to +10V, etc.).The only problem
here is that the internal clock and switch-drive section will not operate until some
positive voltage has been generated.
