LM2586S-ADJ

The LM2586S-ADJ from On Semiconductor is a versatile DC DC converter IC that supports flyback, step-up (boost), and forward converter topologies. It is designed for applications requiring a wide input voltage range, from 4V to 40V, and provides an adjustable output voltage from 1.23V to 60V.

Key electrical specifications include a minimum switch current limit of 3A and a typical limit of 4A. The switching frequency is adjustable between 75kHz and 125kHz, with a maximum duty cycle of 98%. It features external shutdown capability, drawing less than 60µA when shut down, and includes an internal soft-start function to manage in-rush current. The device is protected by current limit, under-voltage lockout, and thermal shutdown.

Packaged in a TO-263 (DDPAK) surface mount package, the LM2586S-ADJ operates within a temperature range of -40°C to 125°C. Its design requires few external components, making it a cost-effective solution for various power supply designs. Typical applications include simple boost regulators and multiple-output regulators.

This part is marked as NRND (Not Recommended for New Designs) and is obsolete, indicating that manufacturers have discontinued its production. It is recommended to consider alternatives for new designs.
