TC7662 switching voltage doubler, inverter ic (X5)
Converts a +3V to +18V input to a corresponding -3V to -18V output using only two low cost capacitors. 40 mA output current. Get the voltages you need to power OpAmps, LCD's, and other parts from low-cell-count battery sources.
- 97% Power conversion efficiency
- Can combine to get desired voltage/current from battery powered circuits.
Can obtain the following functions (see data sheet):
VOLTAGE DOUBLER provides twice the input voltage
SPLITTING a supply in 2 halves: Positive and negative rails
VOLTAGE INVERTER provides an equal and negative voltage to the input voltage
PARALLELLING of devices increases output current beyond 40 mA
CASCADING devices multiplies output voltage.
All circuits described in data sheet
