    Products Detail

    The PT6400 Series is a 3A integrated switching regulator that converts 5V input to adjustable output voltages (1.2V to 3.8V) with up to 85% efficiency. It requires only two external capacitors for operation and features a compact SIP footprint. Designed for standalone use (not parallelable), it allows easy integration of low-voltage logic ICs into 5V systems. Output voltage is adjustable with a single external resistor. Note: Does not include short-circuit protection.

    Key Features

    • Single-device 5V to 3V power, 85% efficiency, Small SIP footprint, Adjustable output voltage, Requires only two external capacitors, Standalone operation, Output current up to 3A, Input voltage range 4.5V-5.5V

    Application scenarios

    • Integration of low-power 3.3V logic into 5V systems
    • terminating high-speed data buses (Futurebus, GTL)
    • power supply for various low-voltage ICs
