onsemi DC DC Switching Controllers NCP5424DG

The NCP5424DG is a dual N-Channel synchronous buck controller designed for high efficiency and flexibility in power management applications. It utilizes V2 control for rapid transient response and excellent line and load regulation. This controller can be configured for either a single two-phase output or as two independent out-of-phase controllers, making it suitable for applications requiring current sharing from multiple input sources, such as video graphics cards and DDR memory power supplies. Key features include hiccup mode current limit protection for Controller 1, cycle-to-cycle current limit for Controller 2, and programmable soft-start functionality. The device supports a wide frequency range from 150 kHz to 600 kHz, with the switching frequency adjustable via a single resistor. Additional protections include undervoltage lockout and built-in adaptive FET non-overlap time to prevent shoot-through conditions. The NCP5424DG is packaged in a Pb-free SOIC-16 format, making it compatible with various PCB designs. Its capabilities and protections make it a strong candidate for engineers looking for reliable and efficient power management solutions in high current applications.
