APPLICATION INFORMATION
The TPS4000x series of synchronous buck controller devices is optimized for high-efficiency dc-to-dc
conversion in non-isolated distributed power systems. A typical application circuit is shown in Figure 1.
The TPS40007 and TPS40009 are the controllers of choice for general-purpose synchronous buck designs.
They are designed to startup into applications where the output voltage is pre-biased, and without having the
synchronous rectifier interfere with the pre-bias condition. PWM pulses are enabled when the soft-start voltage
crosses the feedback level dictated by the pre-bias output. Moreover, the pre-biased output ramps up smoothly
from its pre-bias value and into regulation.
