onsemi DC DC Switching Controllers CS5211EDR14

The CS5211EDR14 is a low voltage synchronous buck controller designed for efficient DC-DC conversion using external N-Channel MOSFETs. It features high current internal gate drivers that enhance efficiency by driving low RDS(on) NFETs effectively. The controller employs V2,Ñ¢ control architecture, which provides excellent transient response and simplifies loop compensation. This device operates within a voltage range of 4.5 V to 14 V and supports adjustable fixed frequency operation from 150 kHz to 750 kHz, allowing flexibility in efficiency and component size. Key protective features include overcurrent protection, undervoltage lockout, and hiccup mode short circuit protection. The CS5211EDR14 also includes programmable soft-start functionality and differential remote sense capability for improved performance in power management applications. Packaged in a 14-pin SOIC format, the CS5211EDR14 is suitable for various applications requiring reliable and efficient power regulation.
