PMIC - Gate DriversCHL8510CRT Application Field and Working PrincipleThe CHL8510CRT switched-capacitor buck regulator is a buck-boost regulator suitable for a variety of buck-boost design applications. It is primarily intended for use in commutating and continuous-conduction applications. As its name implies, the CHL8510CRT utilizes two synchronous switches to provide bidirectional voltage conversion and energy transfer between the input and the output. The CHL8510CRT is designed to provide a current source/sink of up to 2.25A, making it suitable for a variety of technologies. It is suitable for wide-input voltage applications, up to 26V. This also makes it suitable for applications that require a wide dynamic range in input voltage, for example, solar-powered systems. With an operating range between 0.9V and 5.5V, the CHL8510CRT can also be used in battery-powered applications. The CHL8510CRT works by controlling switches and capacitors to store and transfer energy from the input voltage to the output voltage. When the voltage at the input is greater than the voltage on the output, the net voltage across the switches is positive, and so the switches are turned on, allowing current to flow between the input and output. As the voltage on the output increases, the voltage across the switches decreases and the switches are turned off. The energy is then stored on a capacitor, which is then used to provide energy to the output when the input voltage is less than the output voltage. The CHL8510CRT also features a comprehensive suite of features to further optimize energy transfer and design flexibility. These features include a selectable frequency range, a current limit, and a low quiescent current. The CHL8510CRT is also designed to provide a maximum efficiency of 97.2%, eliminating the need for a heatsink in many applications. It also includes integrated ESD protection and is available in a small 16-pin TSSOP package. The CHL8510CRT is a highly efficient and versatile switched-capacitor buck-boost regulator, suitable for a variety of buck-boost applications, including wide-input voltage applications and battery-powered applications. It provides up to 2.25A current source/sink, and provides up to 97.2%, making it a great choice for energy-sensitive applications. It also includes a comprehensive feature set, such as a selectable frequency range, a current limit, and a low quiescent current, and is available in a small TSSOP package.
