The LM2591HVSX-ADJ is a monolithic integrated circuit from Texas Instruments, designed as a simple, high-efficiency step-down (buck) switching regulator. It is capable of driving a 1-A load with excellent line and load regulation.
This regulator operates at a fixed switching frequency of 150 kHz, allowing for the use of smaller filter components compared to lower-frequency regulators. It is available in fixed output voltages of 3.3V and 5V, as well as an adjustable version with an output voltage range from 1.2V to 57V. The input voltage range extends up to 60V.
Key features include ON/OFF control, low power standby mode with typical quiescent current of 90 μA, thermal shutdown, and current-limit protection. The device requires a minimum number of external components for operation and includes internal frequency compensation.
The LM2591HV series is available in a standard 5-pin package, including surface mount options like DDPAK/TO-263 and through-hole options like TO-220. This makes it suitable for various on-card switching regulator applications.
