TEXAS INSTRUMENTS LM2587T-ADJ 直流-直流开关升压, 反激稳压器, 可调, 4V-40V输入, 1.23V-60V/5A输出, 100 kHz, TO-220-5
The is a SIMPLE SWITCHER® Flyback Regulator specifically designed for flyback, step-up boost and forward converter applications. Requiring a minimum number of external components, this regulator is simple to use. Included in the datasheet are typical circuits of boost and flyback regulators. 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 5A NPN device that can stand-OFF 65V. Protecting the power switch are current and thermal limiting circuit 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 start up, current mode control for improved rejection of input voltage and output load transients and cycle-by-cycle current limiting.
