    Products Detail

    The PT6400 Series is a 3A, 5V input adjustable Integrated Switching Regulator (ISR) that provides a single-device solution for 5V to 3V power conversion. It allows easy integration of low-power 3.3V logic ICs into existing 5V systems without redesigning the central power supply. The regulator requires only two external capacitors for operation and features adjustable output voltage via one external resistor. Models PT6406, PT6407, and PT6408 can be used to terminate high-speed data buses such as Futurebus (+2.1V) or GTL (+1.2V) logic buses. Note: This product does not include short circuit protection.

    Key Features

    • Single-Device 5V to 3V Power
    • 85% Efficiency
    • Small SIP Footprint
    • Only two external capacitors required
    • Adjustable Output Voltage
    • Stand alone (not parallelable) operation
    • Output Current: 3A
    • Input Voltage: 4.5V to 5.5V
    • Switching Frequency: 500-800 kHz
    • Operating Temperature: 0 to +70°C (recommended)
    • No short circuit protection

    Application scenarios

    • Integration of low-power 3.3V logic ICs into 5V systems
    • termination of high-speed data buses (Futurebus, GTL)
