DC-DC converters are widely used in the control, supply and conversion of power in industrial and consumer electronic applications. The PT6646E is a 6-terminal, two-channel DC-DC converter designed specifically for low-power applications. It can be used to convert a single power source from a battery or a wall power supply to two separate voltage levels, either within the same channel or across two independent channels. As a low power two-channel DC-DC converter, the PT6646E offers designers a cost-effective and efficient solution for powering components and circuits in embedded embedded systems and mobile applications.

PT6646E converter is based on a buck and boost operation, which allows for a wide input voltage range and high efficiency. The converter provides two independent channels, each capable of supplying up to 200mA with a maximum output voltage of 5 volts. The dedicated input and output terminals allow for easy wiring and provide precise output voltage regulation. The converter also features power-good indication as well as undervoltage, and overvoltage protection.

The PT6646E is powered by Low VCE (SAT) IGBT semiconductor devices. The device operates in a continuous current mode, using a pulse width modulation (PWM) controller that enables it to respond quickly to changing load scenarios. This allows for efficient, clean and reliable power conversion. The IGBTs have no reverse recovery losses, no temperature rise at full load, and can support high efficiency with no audible noise or overshoot.

PT6646E has many applications in the embedded embedded systems and mobile applications. It can be used to provide power to digital signal processor (DSP) and micro-controllers, wireless modules, cellular phones, netbooks, tablets, digital cameras, and other low to medium power devices. As a low power two-channel DC-DC converter, the PT6646E is also well suited for automotive applications, where it can provide power for navigation systems, backlighting controls, and other auto accessories. Additionally, it can be used in medical devices, such as blood glucose monitors and pulse oximeters, as well as in renewable energy applications, such as solar and wind generation.

The PT6646E converter is composed of two channels. Each channel consists of a buck regulator that is made up of an input capacitance to filter incoming voltage, an inductor and two FET switches that control the output voltage. The buck regulator is also equipped with an undervoltage lockout circuit and a low RDS(ON) switch for power savings. The boost regulator consists of an inductor, two FET switches, a capacitor, and a current-mode control circuit. The converter is also designed with a power-good indicator, an enable input, an auxiliary output, and an enable output for driving an external MOSFET switch.

The PT6646E converter can be used to supply power to a wide variety of applications, is extremely efficient and reliable, and is designed with safety protections for superior performance. It offers a cost-effective and efficient solution for powering components and circuits in embedded embedded systems and mobile applications.
