IC REG CTRLR BUCK 5TSOPManufacturer: onsemi
Categories: DC DC Switching Controllers
Quality Control: Learn More
The onsemi NCP1550SN18T1 is a highly efficient, fixed-frequency buck (step-down) DC-DC controller designed for positive output voltage regulation. This single-output device operates at a switching frequency of 600kHz, enabling the use of smaller external components. The NCP1550SN18T1 features an enable pin for flexible control and a maximum duty cycle of 100%, suitable for applications requiring continuous power delivery. Its 2.45V to 5.5V input voltage range and transistor driver output configuration make it ideal for power management in consumer electronics, industrial automation, and battery-powered devices. The component is supplied in a 5-TSOP surface-mount package on tape and reel.
