RT9076-15GVN is an advanced member of Richtek’s voltage regulator family. It is a linear voltage regulator specifically designed for portable applications where size and power efficiency are critical such as hand-held devices and computer peripherals. RT9076 adopts CMOS technology which significantly reduce its quiescent current while maintaining a high level of system performance. Additionally, it features excellent line and load regulation, low output noise, and temperature tracking.

RT9076-15GVN offers a wide voltage input range of 3.2V to 16V and can output up to 15V, with 5% accuracy. It integrates a power MOSFET that helps to maintain a very low on-resistance structure allowing it to operate with a maximum of 100mA output current and a minimum dropout voltage of 0.15V. The device is available in SOP-8 and DFN-6 packages, making it suitable for applications such as fixed output power supply, on-board DC-DC conversion, and Portable USB applications.

The device’s operating mode is designed to selectively operate in either Autoswitching or PFM mode. When operating in Autoswitching mode, the RT9076-15GVN will automatically select between DC-DC Buck (Step-down) or Boost (Step-up) mode depending on the output voltage. This will ensure the highest efficiency. When operating in PFM mode, the device will modulate the frequency depending on the load current, allowing it to achieve higher efficiency and a lower overall power consumption. The device also features a soft start function which will limit the inrush current during start-up.

In addition, RT9076-15GVN also implements an Over-Temperature protection circuit. This will limit the power dissipation within the device, keeping the component temperature under control and preventing any damage. In the event of an over-temperature condition, the device will temporarily shut off, allowing it to cool down before automatically restarting. This feature makes the device highly reliable and suitable for automotive application.

In summary, RT9076-15GVN is an ideal option for applications requiring high efficiency, low power consumption and an overall compact and lightweight design. With its extensive features and low quiescent current operation, it is the perfect solution for modern Portable USB and automotive applications.
