TPS40140RHHT Functional Block Diagram

The TPS40140RHHT operates with a programmable fixed switching frequency. It is a current feedback controller with forced phase current balancing. When compared to voltage mode control, the current feedback controller results in a simplified feedback network and reduced input line sensitivity. Phase current is sensed by using either the DCR (direct current resistance) of the filter inductors or current sense resistors installed in series with the output. See the section on INDUCTOR DCR CURRENT SENSE. The current signal is then amplified and superimposed on the amplified voltage error signal to provide current mode  PWM  control.
Other features include a programmable input under-voltage lockout (UVLO), differential input amplifier for precise output regulation, user-programmable operation frequency, programmable pulse-by-pulse overcurrent protection, and output under-voltage shutdown and re-start, capacitor to set soft-start time and power good indicators.
