                      Product Overview

                      LT8301 is a 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 a single external resistor. Internal compensation and soft-start further reduce external component count. 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 1.2A, 65V DMOS power switch is integrated along with all high voltage circuitry and control logic into a 5-lead Thin SOT™ package.

                      • 2.7V to 42V input voltage range and deliver up to 6W of isolated output power
                      • Low quiescent current: 100µA in sleep mode, 350µA in active mode
                      • Boundary mode operation at heavy load, low-ripple Burst Mode® operation at light Load
                      • Minimum load <lt/>0.5% (typ) of full output
                      • VOUT set with a single external resistor
                      • No transformer third winding or opto-isolator required for regulation
                      • Accurate EN/UVLO threshold and hysteresis
                      • Internal compensation and soft-start, output short-circuit protection
                      • Operating temperature range from –40°C to 125°C
