The CS5173ED8 is a 560 kHz DC-DC switching regulator capable of delivering up to 1.5 A of output current. It operates over a wide input voltage range of 2.7 V to 30 V, making it suitable for various power supply configurations, including boost, flyback, forward, inverting, and SEPIC. The device features a current mode architecture that ensures excellent load and line regulation, along with built-in overcurrent protection and thermal shutdown with hysteresis. This regulator is designed for high efficiency and compactness, allowing for the use of smaller external components. It supports both positive and negative voltage regulation and includes provisions for frequency synchronization and shutdown functionality. The CS5173ED8 is pin-to-pin compatible with LT1372/1373, facilitating easy integration into existing designs. It is available in a Pb-free, halogen-free package and is RoHS compliant, with an industrial temperature range of -40¬8C to 125¬8C.
