    Products Detail

    The PT6640 series is a family of DC-DC converters that provide negative output voltages from a positive input voltage. They feature adjustable output voltage, remote sense capability, and up to 85% efficiency. Packaged in a 14-Pin SIP (Single In-line Package) with surface-mount options, these converters require external electrolytic capacitors (560µF input, 330µF output) for proper operation. They support output currents from 1.5A to 4A depending on the model.

    Key Features

    • Wide Input Voltage Range: +8V to +27V
    • Negative Output: -2.5V/4A to -15V/1.5A
    • Adjustable Output Voltage
    • Efficiency up to 85%
    • Remote Sense Capability
    • 14-Pin SIP and surface-mount package
