General Description
The D2587A series regulator is a monolithic integrated circuit designed for trans, boost and forward converter applications. The device is available in four different output voltage versions: 3.3V, 5V, 12V, and adjustable voltage. These regulators require few external components, and thus are cost-effective and easy to use. Typical boost and trans regulator circuits are included in the data sheet.
Also listed are selection guidelines for diodes and capacitors and standard inductors and anti-type transformers designed for operating in conjunction with the above switch regulator. The power switch is a 5A NPN device that cuts off a 65V voltage. The power switches are protected by current and thermal restriction circuits and undervoltage locking circuits. This IC contains a 100kHz fixed-frequency internal oscillator that allows the use of small magnets. Other features include soft start modes that reduce the surge current during startup, improved current mode control functions that suppress the input voltage and output load transients, and periodic current limits. The power system ensures output voltage tolerance for different lines and load conditions is ± 4%.
The D2587A is available in TO220-5 and TO263-5 package.
