Полупроводники - Микросхемы\Микросхемы Управления Питанием\DC - DC Устройства Управления Питанием\DC - DC КонтроллерыLT8302 is a monolithic micropower isolated flyback converter. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no third winding or opto-isolator for regulation. The output voltage is programmed with two external resistors and a third optional temperature compensation resistor. Boundary mode operation provides a small magnetic solution with excellent load regulation. Low ripple Burst Mode operation maintains high efficiency at light load while minimizing the output voltage ripple. A 3.6A, 65V DMOS power switch is integrated along with all the high voltage circuitry and control logic into a thermally enhanced 8-lead SO package. The high level of integration and the use of boundary and low ripple burst modes result in a simple to use, low component count, and high efficiency application solution for isolated power delivery. Applications include industrial, medical power supplies, isolated auxiliary/housekeeping power supplies. • 3.6A, 65V internal DMOS power switch• Low quiescent current, 106µA in sleep mode, 380µA in active mode• Quasi-resonant boundary mode operation at heavy load• Low ripple Burst Mode® operation at light load• Minimum load of < 0.5% (typ) of full output• No transformer third winding or opto-isolator, required for output voltage regulation• Accurate EN/UVLO threshold and hysteresis, internal compensation and soft-start• Temperature compensation for output diode, output short-circuit protection• 8-lead plastic SO package, -40°C to 125°C temperature range• Operates from an input voltage range of 3V to 42V and delivers up to 18W of isolated output power
