Description
General part information
MAX829 Series
The MAX828 and MAX829 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.
