Efficient Synchronous Rectified Buck Controller - UP1542S - Compact and Easy-to-Use

The UP1542SSU8 is a highly efficient and compact synchronous rectified buck controller designed for reliable power supply applications. With the ability to operate from both 5V and 12V supply voltages, it offers versatility in various system designs. This controller is capable of generating output voltages as low as 0.6V for linear OCP (Over Current Protection).

Optimize Power Supply Integration with UP1542S SOP-8 Buck Controller

Featuring a constant frequency and voltage mode control scheme, the UP1542SSU8 ensures stable and consistent performance. Its low external component count and fast transient response make it easy to use and optimize integration, reducing both size and cost of the power supply.

The UP1542SSU8 offers additional useful features to enhance power supply reliability. It includes internal soft-start for controlled startup, over/undervoltage protection to safeguard against voltage fluctuations, overcurrent protection for improved system protection, and a shutdown function for power saving when not in use.
