Product Summary
The MAX860ISA+T charge-pump voltage converter inverts input voltages ranging from +1.5V to +5.5V, or double input voltages ranging from +2.5V to +5.5V. Because of their high switching frequencies, the MAX860ISA+T uses only two small, low-cost capacitors. Their 50mA output makes switching regulators unnecessary, eliminating inductors and their associated cost, size, and EMI. Greater than 90% efficiency over most of the load-current range, combined with a typical operating current of only 200μA (MAX860ISA+T), provides ideal performance for both battery-powered and board-level voltage-conversion applications.
