8 Detailed Description
8.1 Overview
The TPS40140 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
direct current resistance (DCR) of the filter inductors or current sense resistors installed in series with the output.
See the section 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 programmable input undervoltage lockout (UVLO), differential input amplifier for precise
output regulation, user programmable operation frequency, programmable pulse-by-pulse overcurrent protection,
output undervoltage shutdown and restart, capacitor to set soft-start time and power good indicators.
The TPS40140 is a versatile controller that can operate as a single controller or 'stacked' in a multi-controller
configuration. A TPS40140 has two channels that may be configured as a multi-phase (single output) or as a
dual, with two independent output voltages. The two channels of a single controller always switch 180° out-of-
phase. See the Feature Description for further discussion on the clock and voltage master and clock and voltage
slave.
Some pins are used to set the operating mode, and other pins' definition change based on the mode selected.
