Product Overview
LTC3708 is a dual, 2-phase synchronous step-down switching regulator with output voltage up/down tracking capability. The IC allows either coincident or ratiometric tracking. Multiple devices can be daisy-chained in applications requiring more than two voltages to be tracked. Power supply sequencing is accomplished using an external soft-start timing capacitor. It uses a constant on-time, valley current mode control architecture to deliver very low duty factors without requiring a sense resistor. Operating frequency is selected by an external resistor and is compensated for variations in input supply voltage. An internal phase-locked loop allows the IC to be synchronized to an external clock. Fault protection is provided by an output overvoltage comparator and an optional short-circuit shutdown timer. The regulator current limit level is user programmable. It is used in application such as digital signal processors, network servers etc.
- Minimum on-time is 85ns typical at (ION = 180µA, TA = 25°C. VCC = 5V, DRVCC = 5V)
- No RSENSE™ option for maximum efficiency, external frequency synchronization
- Very fast transient response, programmable output voltage up/down tracking
- 2-phase operation reduces input capacitance, external frequency synchronization
- Internal reference voltage is 0.6V typ at (ITH = 1.2V, 0°C to 85°C)
- Adjustable cycle-by-cycle current limit
- Instant output overvoltage protection
- Optional short-circuit shutdown timer, PGOOD delay is 100µs min at (TA = 25°C, VCC = 5V)
- Operating temperature is -40°C to 85°C, package style is 32-lead plastic QFN
