LT8301IS5#TRMPBF, Switching Voltage Regulators 42VIN uP No-Opto Iso Fly Conv w/ 65V/1.2
Semiconductors\Power Management ICs\Voltage Regulators & Voltage Controllers\Switching Voltage Regulators
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 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
