Product's Name:
LTC3807EUDC Low Iq synchronous step-down controller with 24V output
voltage capability
L3+ step-down chip U73 position 24V synchronous step-down
controller temperature controller chip QFN20 LTC3807EUDC LGSG
Product description:
The LTC3807EUDC is the controller of the LTC3807 family, commonly
referred to as the 714 LGSG, and the device is marked "LGSG".
Commonly used in L3+ hash board step-down chip U73 position 24V
output synchronous step-down controller.
The LTC3807EUDC is a high-performance step-down switching regulator
DC/DC controller that drives an all N-channel synchronous power
MOSFET stage. A constant frequency current mode architecture allows
a phase-lockable frequency of up to 750kHz.
The LTC3807 features a precision 0.8V reference and power good
output indicator. A wide 4V to 38V input supply range encompasses a
wide range of intermediate bus voltages and battery chemistries.
The output voltage of the LTC3807 can be programmed between 0.8V to
24V. The TRACK/SS pin ramps the output voltages during start-up.
Current foldback limits MOSFET heat dissipation during
short-circuit conditions. The PLLIN/MODE pin selects among Burst
Mode operation, pulse-skipping mode, or continuous conduction mode
at light loads.
