    Products Detail

    PM6644 Overview


    optimized performance is achieved by utilizing the Tube package in this voltage regulator. Throughout this voltage regulator, there are 10 terminations. There are two types of analog ICs in this voltage regulator 12v: SWITCHING REGULATOR ICs, which are the ones used in older voltage regulator 12vs. The space-saving 10-VFDFN Exposed Pad package is available for this voltage regulator. The voltage regulator 12v has 1 outputs. The adjusting voltage regulator generates Adjustable (Fixed) output. As the name implies, this voltage regulator 12v is designed for mounting on a Surface Mount bracket. During switching regulator operation, the operating temperature should remain at -40°C~125°C TJ. This voltage regulator 12v reaches a switching frequency of 200kHz~600kHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 4.5V. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.9V 3.47V. There is a maximum input voltage of 25V for this voltage regulator 12v. The voltage regulator 12v is designed to provide a nominal input voltage of 12V for operation. In terms of category, this voltage regulator 12v falls into the Switching Regulator or Controllers category. In the particular voltage regulators, the PM6644 family is represented. A voltage of 3.47V volts can be generated by DC DC switching regulator. There are 10 pins used for switching regulator operation. For this switching regulator, we recommend keeping the output voltage at at least 900mV volts. A 350mA A maximum output current is required to meet the switching regulator operation requirements. By using the 8V's maximal output voltage, adjusting voltage regulator can operate easily. With a maximum output voltage of 8V, DC DC switching regulator has a very high efficiency. With 4.2V as the supply voltage, this DC-DC switching regulator will operate.
