MAX6800UR44D3+T - Brand New Maxim Integrated IC Chips
-
Description
The MAX6800UR44D3+T is a monolithic, CMOS, dual charge-pump voltage converter specifically designed to provide ±10V outputs from a +5V input voltage. It features a positive step-up charge pump to generate +10V from +5V input and an inverting charge pump to produce the -10V output. The device has an on-chip 8kHz oscillator and offers a voltage-conversion efficiency of 95% and a power-conversion efficiency of 85%. With a voltage range of +2V to +6V, this converter requires either four external capacitors (MAX680) or no capacitors (MAX681) to produce the desired voltages. The MAX6800UR44D3+T is suitable for various applications that require both positive and negative voltages from a single supply.
