LM2594HM-ADJ - Brand New National Semiconductor IC Chips
-
Description
The LM2594HM-ADJ is a monolithic integrated circuit regulator designed for easy and convenient design of a step-down switching regulator (buck converter). It has excellent line and load regulation and is capable of driving a 0.5A load. This device is available in an adjustable output version and is internally compensated to simplify power supply design.
Compared to popular three-terminal linear regulators, the LM2594HM-ADJ has higher efficiency, especially with higher input voltages. It operates at a switching frequency of 150kHz, allowing for smaller sized filter components. It is available in a standard 8-Lead PDIP and 8-Lead Surface Mount packages. The LM2594HM-ADJ also features a guaranteed 4% tolerance on output voltage and 15% on the oscillator frequency. It includes external shutdown and self-protection features such as switch cycle-by-cycle current limit and thermal shutdown.
