The RT7264EZSP is a DC-DC Buck Switching Regulator ideal for power management in consumer and industrial electronics applications. It converts an input voltage from a wide range of sources, such as batteries or wall adapters, into a regulated output voltage. This can be used to provide power to microprocessors, memory and other sensitive logic. The RT7264EZSP is designed with advanced technology in order to provide key features such as a very high switching frequency, high efficiency and low noise operation.

The main features of the RT7264EZSP are as follows:

• Input Voltage Range: 2.5V to 18V.
• Output Voltage Range: 0.6V to 12V.
• High Efficiency: ≧ 90%
• High Switching Frequency: > 300 kHz
• Low Noise: < 65 μV
• Thermal Shutdown Protection
• Programmable Soft-Start
• Programmable Maximum Duty Cycle

The RT7264EZSP operates using a synchronous control loop, which includes a feedback loop, a control unit and an error amplifier. The feedback loop contains a voltage divider connected to the output voltage, which regulates the output voltage to the desired reference voltage. The control unit is responsible for controlling the type of operation (buck or boost), the frequency of the switching cycle and the duty cycle, which determines the amount of power put in to the output. The error amplifier is then used to compare the feedback loop’s output with the reference voltage, in order to generate a control signal to the control unit. This creates a closed loop system that provides accurate voltage regulation.

The RT7264EZSP is ideal for applications such as portable electronics, notebook computers, consumer electronics, industrial control and communications equipment. With its high efficiency, low noise operation and wide input voltage range, it is the perfect solution for powering your devices.
