LTC3810EG#PBF

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. This uses a constant on-time valley current control architecture to deliver very low-duty cycles with accurate cycle-by-cycle current limits, without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifier provides a very fast line and load transient response. Application includes 48V telecom and base station power supplies, networking equipment, serves, automotive and industrial control systems.

• No current sense resistor required
• Dual N-channel MOSFET synchronous drive
• Extremely fast transient response
• Programmable output voltage tracking/soft-start
• Synchronizable to external clock, selectable pulse skip mode operation
• Power good output voltage monitor
• INTVCC supply voltage range from 6.35 to 14V (TA = 25°C)
• 28-lead plastic SSOP package
• Temperature rating range from -40°C to 125°C
