Product Overview

The LM2585T-ADJ/NOPB is a SIMPLE SWITCHER® step-up Flyback Regulator for use with forward converter. Requiring a minimum number of external components, this regulator is simple to use. Included in the datasheet are typical circuits of boost and flyback regulator. Also listed are selector guides for diodes and capacitors and a family of standard inductors and flyback transformers designed to work with these switching regulators. 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 undervoltage lockout circuit. This IC contains a 100kHz fixed-frequency internal oscillator that permits the use of small magnetic. Other features include soft-start mode to reduce in-rush current during startup, current-mode control for improved rejection of input voltage and output load transients and cycle-by-cycle current limiting.
  • 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 startup
  • Output transistor protected by current limit, undervoltage lockout and thermal shutdown
  • System output voltage tolerance of ±4% maximum over line and load conditions
