It is designed specifically for VRM (Voltage Regulator Module) applications and features an integrated low RDS(ON) topology for outstanding performance. The integrated switch also ensures low switching losses and high efficiency, making it suitable for a wide range of applications. Additionally, it features internal compensation, allowing it to be used in a wide range of applications.

The VI-B4B-CY-F2 features a wide input voltage range of 5V to 48V and can handle input voltages up to 66V in certain applications. It supports multiple output voltages including 5V, 8V, 12V, 16V, 20V, and 24V. It also supports multiple output current configurations, with a typical output current of 2A and a maximum output current of 4A. Additionally, it can provide an input current addressable current limit up to 8A. The VI-B4B-CY-F2 also features an automatic green-mode function, which helps to reduce power consumption under light load conditions.

The basic operating principle of the VI-B4B-CY-F2 is synchronous buck conversion. In this operating mode, the integrated switch operates at a frequency determined by an external clock signal. During normal operation, the switch is open and the input voltage is applied to the output. Then, the switch is closed for a short period of time, allowing for regulated dc voltage conversion. During the short period of time when the switch is closed, the output voltage is regulated by the current being drawn from the output. The maximum frequency of operation of the VI-B4B-CY-F2 is 500 kHz.

The VI-B4B-CY-F2 is highly integrated and features several protections to ensure safe and reliable operation. It features an integrated VGS driver, over-current protection, over-temperature protection, short circuit protection, and under-voltage protection. Additionally, its low RDS(ON) switching topology helps to reduce EMI (Electromagnetic Interference) and RFI (Radio Frequency Interference) noise, ensuring reliable operation in the most demanding applications.

The VI-B4B-CY-F2 is an ideal DC-DC converter solution for applications requiring low output voltages and high efficiency. It features an integrated low RDS(ON) switching topology for outstanding performance and is highly integrated for easy implementation. It also features several protection features to ensure safe and reliable operation and can handle input voltages up to 66V in certain applications. Additionally, its synchronous buck operating principle provides excellent power efficiency and thermal performance, while its automatic green-mode function helps to reduce electricity consumption under light load conditions.
