The PT6651M is a DC/DC converter specifically designed for cost-sensitive applications. It offers high efficiency and low stand-by power, with an adjustable output voltage ranging from 0.8–6 volts (V). The PT6651M is available in an Industry Standard 7-pin SIP (Single Inline Package) and is approved by UL and is compliant with IEC/EN60742 Safety Standard.
The PT665M DC/DC converter uses a continuous conduction mode (CCM) and fixed frequency PWM (Pulse Width Modulation) to achieve high efficiencies. It features both open-loop (current mode) and closed loop (voltage mode) operation for improved power density, output transient and current performance. It is also capable of operating in a wide range of input voltages of 6–24 volts (V).
The PT6651M DC/DC converter has an operating frequency of 1.2 MHz, which allows it to minimize the required board space. It also provides excellent output transient performance and peak current load for applications such as motor drives and medical electronics. Its low stand-by power consumption (4 mW/A) makes it ideal for battery operated systems such as mobile phones and portable devices. It also has an input overvoltage protection feature and an over temperature protection feature for improved reliability. In addition, it is compliant with the medical standards of EMI/ESD.
The PT6651M DC/DC converter provides an adjustable output voltage of 0.8 to 6 V in steps of 0.1V. In addition, it has high current density, up to 2A, and its output accuracy is temperature-independent. It is also designed to be reverse-polarity protected, making it suitable for a wide variety of designs. In addition to its high efficiency, the PT6651M also provides excellent line and load regulation. It is UL-approved, so it allows for a wide variety of applications and is often used in medical electronics systems.
The working principle of the PT6651M is based on the transformation of a constant voltage source in the range of 6–24 V to an output voltage of 0.8–6 V. The input and output terminals are connected in parallel with the high power switch of the converter. When the switch is on, the energy stored in an inductor is transferred to the capacitor until the voltage at the output is equal to the desired output voltage. When the voltage is equal to the desired output voltage, the switch turns off, thus allowing the inductor to store the energy and discharge it to the output when needed. This process is repeated many times in a cycle, thus providing a continuous output voltage.
In conclusion, the PT6651M is a DC/DC converter specifically designed for cost-sensitive applications, offering an adjustable output voltage of 0.8–6 V and high efficiency. It also features open-loop and closed-loop operation, low stand-by power consumption and improved transient response. Furthermore, it has an input overvoltage protection feature, an over temperature protection feature and is UL-approved. With its improved power management features and high efficiency, the PT6651M is capable of providing reliable operation and maximum value in a variety of applications.
