    Products Detail

    The PT6440 series are high-performance Integrated Switching Regulators (ISRs) with 6A output current, operating from input voltages as low as 3.1V to produce adjustable low-voltage outputs (down to 1.0V). They feature a thermally efficient solderable copper case, small footprint (0.61 in²), and support both through-hole and surface mount configurations. Key capabilities include external output voltage adjustment, On/Off inhibit function, short-circuit protection, and standby mode. Requires 100µF input and 330µF output capacitors for proper operation.
