LTC3878IGN#PBF

LTC®3878 is a synchronous step-down switching DC/DC controller optimized for high switching frequency and fast transient response. The constant on-time valley current mode architecture allows for a wide input range, including very low-duty factor operation. No external sense resistor or slope compensation is required. This pin is compatible with in applications that do not use EXTVCC while offering better efficiency. Consult with the factory to verify compatibility. Application includes distributed power systems, embedded computing, communications infrastructure.

• Extremely fast transient response
• Stable with Low ESR ceramic COUT
• Supports smooth start-up into pre-biased output
• Optimized for high step-down ratios
• Power good output voltage monitor
• Input operating voltage range from 4 to 38V (TA = 25°C, VIN = 15V)
• Typical feedback reference voltage is 0.8V (ITH = 1.2V, TA = 25°C)
• 16-lead plastic SSOP package
• Temperature rating range from -40°C to 85°C
