The MAX861ESA+T is a versatile charge pump voltage converter designed by Analog Devices / Maxim Integrated. This component can invert or double input voltages ranging from +1.5V to +5.5V, making it suitable for various power management needs in portable devices.
Key electrical specifications include a maximum output current of 50mA, eliminating the need for bulky switching regulators and inductors. It operates with selectable switching frequencies of 13kHz, 100kHz, or 250kHz, allowing for optimization of capacitor size and quiescent current. The device boasts high efficiency, reaching up to 87% at a 50mA load, and a low quiescent current of 200µA (for MAX860) and a shutdown current of less than 1µA.
Packaged in an 8-pin SOIC surface-mount package, the MAX861ESA+T is designed for efficient integration into compact electronic systems. Its operating temperature range is -40°C to 85°C, ensuring reliable performance in diverse environmental conditions. Applications include portable computers, medical instruments, and interface power supplies.
This charge pump converter offers a typical output resistance of 12Ω and a voltage drop of 600mV at a 50mA load. The frequency-control pin provides flexibility in optimizing performance for specific design requirements, preventing interference with sensitive circuitry.
