Product Overview: LT8302ES8E#PBF from Analog Devices Inc.

The LT8302ES8E#PBF is a high-performance monolithic flyback regulator from Analog Devices Inc. that simplifies the design of an isolated DC/DC converter. With no optocoupler, third winding, or signal transformer required for feedback since the output voltage is sensed from the primary-side flyback waveform, the LT8302ES8E#PBF provides a compact and efficient solution for many power supply applications.

This innovative product operates over a wide input voltage range of 3V to 100V and can deliver up to 2W of output power, making it an ideal choice for a variety of industrial, automotive, and medical applications. Its internal 1A, 150V power switch contributes to a reduced component count, which in turn enables a more compact and cost-effective power supply design.

The LT8302ES8E#PBF features boundary mode operation, which provides a small magnetic solution with improved load regulation. The device's versatility is further enhanced by its capability to support multiple output voltages with a single transformer by changing the feedback resistor, which is a significant advantage for designers looking to create flexible power supply units.

With a robust set of features such as undervoltage lockout (UVLO), thermal shutdown, and output short-circuit protection, the LT8302ES8E#PBF ensures reliable operation under a variety of conditions. Its low ripple Burst Mode operation maintains high efficiency at low output currents while keeping the output ripple below 20mVP-P.

Available in a thermally enhanced 8-lead SO package, the LT8302ES8E#PBF is designed for optimal thermal performance and space-saving on the PCB. Its operating junction temperature range of -40°C to +125°C allows for use in environments with challenging thermal conditions.

For designers seeking an isolated flyback converter with minimal external components and excellent power efficiency, the LT8302ES8E#PBF from Analog Devices Inc. represents an exceptional blend of performance, ease of use, and reliability.
