LT8304IS8E#PBF

LT8304 is monolithic micropower isolated flyback converter. By sampling the isolated output voltage directly from the primary-side flyback waveform, the parts require no third winding or opto-isolator for regulation. The output voltage is programmed with two external resistors and a third optional temperature compensation resistor. Low ripple burst mode operation maintains high efficiency at light load while minimizing the output voltage ripple. A 2A, 150V 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 mode operation result in a simple to use, low component count, and high efficiency application solution for isolated power delivery. Applications include isolated automotive, industrial, medical, telecom power supplies, isolated auxiliary/housekeeping power supplies.

• Boundary mode operation provides a small magnetic solution with excellent load regulation
• Operates from an input voltage range of 3V to 100V and deliver up to 24W of isolated output power
• 3V to 100V input voltage range, 2A, 150V internal DMOS power switch
• Low quiescent current (116µA in sleep mode, 390µA in active mode)
• Quasi-resonant boundary mode operation at heavy load
• Low ripple burst mode operation at light load, minimum load <lt/> 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
