LM2586T-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2586T-5.0/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a step-up, flyback, or forward regulator. It operates with an input voltage range of 4V to 40V and provides a fixed 5V output at up to 3A switching current. The device utilizes current-mode control for rapid transient response and includes internal frequency compensation. Designed for through-hole mounting in a TO-220-7 package, it supports a junction temperature range from -40°C to 125°C.
