PMIC - Voltage Regulators - Special Purpose

RT9088AGQW is a two-phase buck regulator Special Purpose product developed by Richtek Technology, a well-known analog power management IC (PMIC) company. It is designed to provide 5V and 1.5V output voltage for portable consumer electronics.In general, the RT9088AGQW’s input voltage range is from 3.2V to 14V and its output voltage range from 1.5V to 5V. The total output current is up to 1.8A. It also includes over-current protection and short circuit protection to provide effective power management. Furthermore, this device features a high efficiency, low ripple, low standby current, and other features.The RT9088AGQW is also designed to reduce electromagnetic interference (EMI). To achieve this, Richtek Technology has included an external frequency synchronization function which allows the user to synchronize the switching frequency of their application with external source via a single pin. This feature reduces switching noise and helps minimize EMI. The RT9088AGQW also features low voltage drop out (LDO) and internal under voltage lockout (UVL) to ensure the device remains in its optimal operating range. With its high efficiency and low Drop Out voltage, this device can provide more power with fewer components, saving time and expense.The RT9088AGQW is suitable for lighting, LCD backlight controller, USB charger, Post-regulation, PCMCIA/CardBus, DSP, and other portable devices. Furthermore, this device is manufactured using Richtek Technology’s advanced 0.18-micron CMOS processes and is available in the SOP-16 package. The working principle of the RT9088AGQW is based on a standard buck converter. The output voltage is lower than the input voltage and the output is regulated. Inside the RT9088AGQW, there is an Inductor and two MOS transistors that are used to switch the inductor\'s energy flow. When the MOS transistors turn on, the inductor\'s energy is stored in the inductor. When the MOS transistors turn off, the inductor\'s energy is released and sent to the output. This process is repeated constantly, providing a regulated output voltage.Furthermore, the RT9088AGQW contains a precision voltage reference, a high speed control loop, and an adjustable voltage reference, which allow the output voltage to be varied as needed for different applications. Additionally, there are several programmable features to help improve efficiency, such as switching frequency, soft-start time, and maximum output current. In conclusion, the RT9088AGQW is a highly advanced, reliable and special purpose power management IC from Richtek Technology. It is designed to provide 5V and 1.5V output voltage for portable consumer electronics. The RT9088AGQW also includes a number of features and protection mechanisms to ensure optimal performance. Finally, this device is suitable for many applications, such as lighting, LCD backlight controller, USB charger, Post-regulation, PCMCIA/CardBus, and DSP.
