Specifications

Input Voltage

The LTM4622EY#PBF operates with a recommended input voltage range from 3.6 volts to 20 volts. This range allows the module to work with many common power sources. The device can handle a minimum input voltage of 3.1 volts, but engineers should use 3.6 volts or higher for reliable operation. The absolute maximum input voltage is 22 volts, which should not be exceeded to avoid damage.

• Recommended input voltage: 3.6 V to 20 V

• Minimum input voltage (not recommended): 3.1 V

• Absolute maximum input voltage: 22 V

The input voltage range matches other modules in the same series. Compared to some older modules, the LTM4622EY#PBF supports a lower starting voltage, which gives designers more flexibility.

Output Voltage

The LTM4622EY#PBF provides two adjustable output voltages. Each output can be set anywhere from 0.6 volts to 5.5 volts.
