The NCP1445FR4 is a 560 kHz DC-DC switching regulator designed for high efficiency with a maximum output current of 4.0 A. 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 and inverting converters. The device features current mode architecture, which enhances load and line regulation while providing built-in overcurrent protection and thermal shutdown with hysteresis. The NCP1445FR4 can regulate negative output voltages and includes provisions for external synchronization and shutdown. It is packaged in a PowerFLEX 7-pin format, allowing for a compact design with minimal external components. This regulator is ideal for applications in portable computers, battery-powered systems, and distributed power systems.
