LTC3812-5
60V Current Mode
Synchronous Switching
Regulator Controller
DESCRIPTION FEATURES n The LTC3812-5 is a synchronous step-down switching
regulator controller that can directly step down voltages
from up to 60V input, making it ideal for telecom and
automotive applications. The LTC3812-5 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 60V
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 Soft-Start
Generates 5.5V Driver Supply
Selectable Pulse-Skipping Mode Operation
Power Good Output Voltage Monitor
Adjustable On-Time/Frequency: tON(MIN) < 100ns
Adjustable Cycle-by-Cycle Current Limit
Undervoltage Lockout On Driver Supply …
