LTC3810
100V Current Mode
Synchronous Switching
Regulator Controller
DESCRIPTION FEATURES The LTC3810 is a synchronous step-down switching
regulator controller that can directly step-down voltages
from up to 100V, making it ideal for telecom and automotive applications. The LTC3810 uses a constant on-time
valley current control architecture to deliver very low duty
cycles with accurate cycle-by-cycle current limit, without
requiring a sense resistor. High Voltage Operation: Up to 100V
Large 1Ω Gate Drivers
No Current Sense Resistor Required
Dual N-Channel MOSFET Synchronous Drive
Extremely Fast Transient Response
±0.5% 0.8V Voltage Reference
Programmable Output Voltage Tracking/Soft-Start
Generates 10V Driver Supply from Input Supply
Synchronizable to External Clock
Selectable Pulse Skip Mode Operation
Power Good Output Voltage Monitor
Adjustable On-Time/Frequency: tON(MIN) < 100ns
Adjustable Cycle-by-Cycle Current Limit
Programmable Undervoltage Lockout …
