About the Product
Advanced LTC3807EUDC Buck Regulator for Antminer L3+ Hashboard
Introducing the LTC3807EUDC LGSG Buck Regulator, an advanced and low-IQ synchronous step-down controller designed specifically for the Antminer L3+ hashboard. With its exceptional features and precise performance, this regulator ensures optimal power delivery for efficient mining operations. The LTC3807EUDC is part of the LTC3807 family, known as the 714 LGSG, and offers a wide input voltage range of 4V to 38V, making it highly versatile for various power supply configurations.
Efficient Step-Down DC-DC Controller IC for Enhanced Performance
The LTC3807EUDC features a synchronous power MOSFET stage, which maximizes power efficiency. It includes a TRACK/SS pin for ramping the output voltage during start-up, a precision 0.8V reference for accurate voltage control, and a power good output indicator for monitoring system status. The regulator also offers current foldback and a PLLIN/MODE pin for selecting among Burst Mode operation, pulse-skipping mode, or continuous conduction mode at light loads.
