RT7233GSP is an integrated DC-to-DC switching regulator which monolithically integrates all active components in a single package. It comes in a surface mount SOP-8 package and is designed for cost sensitive applications. It provides an adjustable regulated output without the need for external components and takes charge of dynamic load and line conditions. The RT7233GSP is an economical solution for applications where energy efficiency and reliability are important factors.

The RT7233GSP is a high efficiency, low dropout, low noise DC-to-DC switching regulatory device. It has a wide input voltage range of 2V to 28V. It is well suited for mobile phone applications which require a low noise and extremely low dropout voltage solution. It also supports a wide range of output voltage and power up to 5.5V and 1W respectively. It can provide a stable output current up to 150mA. The overall efficiency of this device is more than 80% at full rated load.

The working principle of the RT7233GSP is based on the use of a single power MOSFET switch which is used to switch the voltage and current applied to the external capacitor which provides the output voltage. A voltage control loop is used for regulating the output voltage. It consists of an error amplifier with a P-type feedback network, an oscillator with a current limiter, and a power MOSFET switch, all interconnected with a voltage control loop. When the output voltage is lower than the reference voltage, the voltage control loop increases the duty cycle of the power MOSFET switch, thus increasing the output voltage. On the other hand, when the output voltage is higher than the reference voltage, the duty cycle is decreased which results in a decrease in the output voltage.

The RT7233GSP is suitable for portable power applications that require a small, low noise and low dropout voltage solution. It is well suited for applications such as cell phones, digital cameras, and personal digital assistants. It is also suitable for applications such as laptop computers, portable media players, and PDAs. It is capable of providing excellent regulation performance with a wide input voltage range and high power density.
