PMIC - Voltage Regulators - DC DC Switching Regulators is a type of device used to regulate the output voltage in a DC power supply system. The A6985F5VTR is a newly developed integrated integrated circuit (IC) with a 2-phase switching regulator controller, which is targeted towards adjustable high-speed, high-current, non-isolated DC/DC 5V applications such as notebook computers and other portable battery-powered equipment. It is designed to provide a stable voltage output to the peripheral devices while minimizing power dissipation.

The A6985F5VTR is particularly suitable for applications that require adjustable high-speed, high-current, non-isolated DC/DC 5V outputs. This IC includes a primary regulator featuring adjustable PWM frequency and current limit protection, along with an adjustable load line controller, both of which are designed to maximize performance and reduce ripple. Additionally, the A6985F5VTR contains an adjustable start-up current source and current-sensing circuit, providing an additional level of protection. The regulators support a wide range of input voltages, from 2.6V to 28V, and the device is of low noise operation.

Using the A6985F5VTR is a simple process, requiring only basic connections and programming. Once connected, the primary regulator senses the input voltage and, depending on the programmed current limit, it will generate an error signal if there is a fault, or an under/overvoltage condition. The A6985F5VTR then uses the error signal and adjusts its frequency and/or current limit accordingly. This ensures stable operation and an accurate output voltage.

The A6985F5VTR features an active PWM voltage-mode control, and includes several features that can enable designers to achieve improved efficiency and lower emissions. For example, the AC and DC output skip modes allow the device to bypass the power stages while keeping the other components active and thus reducing power consumption. It also supports low-voltage startup and wakeup, as well as multi-phase operation, allowing for reduced output ripple.

The A6985F5VTR is a highly efficient DC/DC switching regulator, capable of delivering up to 15 Watts of power without additional heatsinking. It is a highly cost-effective solution for applications that require adjustable, high-speed and high-current, non-isolated 5V DC/DC converters. It is especially suitable for applications that require tight, cost-effective performance and highly efficient operation.
