MAX828SNTR-MAX829SNTR
Switched Capacitor Voltage Converters
---The MAX828/829 are CMOS “charge–pump” voltage converters in
ultra–small SOT–23 5 lead packages. They invert and/or double an
input voltage which can range from +1.5V to +5.5V. Conversion
efficiency is typically >95%. Switching frequency is 12kHz for the
MAX828 and 35kHz for the MAX829.
External component requirement is only two capacitors (3.3μF
nominal) for standard voltage inverter applications. With a few
additional components a positive doubler can also be built. All other
circuitry, including control, oscillator, power MOSFETs are integrated
on–chip. Supply current is 50 μA (MAX828) and 115 μA (MAX829).
The MAX828 and MAX829 are available in a SOT–23 5 lead
surface mount package.
