Product Overview
LTC3879 is a synchronous step-down switching regulator 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. System flexibility is offered through a user-programmable soft-start pin and independent RUN pin. The voltage ramping soft-start function can be programmed with a capacitor or made to track an external reference source. Operating frequency is set by an external resistor and compensated for variations in VIN to offer excellent line stability. Discontinuous mode operation provides high efficiency during light load conditions. A forced continuous control pin allows the user to reduce noise and RF interference. It is used in application such as distributed power systems, embedded computing, communications infrastructure etc.
- Wide VIN range is 4V to 38V
- Extremely fast transient response
- No RSENSE™ valley current mode control
- Stable with low ESR ceramic COUT
- Supports smooth start-up in pre-biased output, optimized for high step-down ratios
- Adjustable output voltage soft-start or tracking, power good output voltage monitor
- Dual N-channel MOSFET synchronous drive, adjustable switching frequency
- Programmable current limit with foldback, output overvoltage protection
- Input DC supply current (normal mode) is 1350μA typ at (TA = 25°C, VIN = 15V)
- Operating temperature is -40°C to 85°C, package style is 16-lead plastic DFN
