LD1085D2M-R is a monolithic switch mode power supply controller which is based on power control IC. It is an integrated circuit for linear voltage regulation, provided with a wide input voltage range and high current capability. It is mainly used for AC/DC or DC/DC converter application, providing excellent load and line regulation along with fast transient response. The LD1085D2M-R is suitable for a wide range of AC/DC or DC/DC converter application fields, such as laptop computers, LCD monitors, set-top boxes, power supplies, and other general purpose applications in the industrial, commercial and consumer markets.

Generally, the basic working principle of the LD1085D2M-R is to convert the input DC voltage into an AC voltage, usually with a pulse-width modulation (PWM) technique. This PWM voltage is then output to the load through a power circuit, such as a coil and electronically-controlled switch or a transformer. The main principle of this linear voltage regulator is that it compares a reference voltage with a feedback voltage at the output and varies the duty cycle to adjust the average output voltage to the programmed reference voltage.

The LD1085D2M-R consists of a sensing section and a power section. The sensing section includes the P07T-035LX regulator IC and the required external components to set the voltage reference, the output voltage and temperature compensation. The power section consists of the P07T-035LX synchronous rectifier IC and the electronic switch, a Schottky diode and the power transformer. This power section is designed to control the pulsed output current from the rectified input voltage to provide a regulated output voltage.

The LD1085D2M-R is designed for use in AC/DC and DC/DC converter applications, such as laptop computers, LCD monitors, set-top boxes, power supplies and other general purpose industrial and commercial applications. With its wide input voltage range and high current capability, the LD1085D2M-R is capable of providing a high power efficiency in most applications. Furthermore, it is equipped with an over-temperature protection circuit, which prevents the output voltage from exceeding the set reference voltage and provides a safe working environment. With its flexible design, it is easy to adjust the output voltage to meet the user’s application requirements.

The LD1085D2M-R is a useful linear voltage regulator with a wide input voltage range and a high current capability. With its various protective features and excellent load and line regulation, the LD1085D2M-R is suitable for a wide range of AC/DC and DC/DC converter applications. With its stable and reliable performance, it is an ideal choice for industrial and commercial applications.
