Product Overview

The LM2585T-ADJ is a SIMPLE SWITCHER® Step-up Wide Vin Flyback Regulator designed for flyback, step-up (boost) and forward converter applications. The device is available in adjustable output voltage version and requiring a minimum number of external components. The power switch is a 3A NPN device that can stand-off 65V. Protecting the power switch are current and thermal limiting circuits and an under-voltage lockout circuit. This IC contains a 100kHz fixed-frequency internal oscillator that permits the use of small magnetics. Other features include soft-start mode to reduce in-rush current during start up, current mode control for improved rejection of input voltage and output load transients and cycle-by-cycle current limiting. An output voltage tolerance of ±4%, within specified input voltages and output load conditions, is specified for the power supply system.
  • Requires few external components
  • Family of standard inductors and transformers
  • Current-mode operation for improved transient response, line regulation and current limit
  • Internal soft-start function reduces in-rush current during start-up
  • Output transistor protected by current limit, under-voltage lockout and thermal shutdown
  • System output voltage tolerance of ±4% maximum over line and load conditions
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
