FUNCTIONAL DESCRIPTION
SLUS602B – JUNE 2004 – REVISED SEPTEMBER 2005
FUNCTIONAL BLOCK DIAGRAM
The TPS40130 uses programmable fixed-frequency, peak current mode control with forced phase current
balancing. When compared to voltage-mode control, current mode 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 output. The first method involves generation of a
current signal with an R-C circuit (shown in the applications diagram). The R-C values are selected by matching
time constants of the RC circuit and the inductor time constant, R×C = L/DCR. With either current sense
method, the current signal is amplified and superimposed on the amplified voltage error signal to provide current
mode PWM control.
Output voltage droop can be programmed to improve the transient window and reduce size of the output filter.
Other features include: a true differential output sense amplifier, programmable current limit, programmable
output over-voltage set-point, capacitor set soft-start, power good indicator, programmable input undervoltage
lockout (UVLO), user programmable operation frequency for design flexibility, external synchronization
capability, programmable pulse-by-pulse overcurrent protection, output undervoltage shutdown and restart.
