4.2 CLOCK MASTER AND CLOCK SLAVE
TPS40140
DUAL OR 2-PHASE, STACKABLE CONTROLLER
www.ti.com
SLUS660F – SEPTEMBER 2005 – REVISED SEPTEMBER 2009
The package is an 36-pin PQFP (RHH) package. The thermal pad is an electrical ground connection.
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 degrees out of phase. See below 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.
It is often necessary to refer to a pin or pins that are used in CH1 and/or CH2. The short cut nomenclature
used is the pin name with a lower case 'x' to mean either or both channels. For example, TRKx refers to
TRK1 and/or TRK2.
A controller may function as a 'Clock master' or a 'Clock slave'. The term ' Clock master' designates the
controller, in a multi-controller configuration, that generates the CLKIO signal for clock synchronization
between the Clock master and the Clock slaves. The CLKIO signal is generated when the 'RT' pin of the
Clock master is terminated with a resistor to ground and the PHSEL pin of the Clock master is terminated
with a resistor, or resistor string, to ground. The 'Clock slave' is configured by connecting the RT pin to
BP5. Then the Clock slave receives the CLKIO signal from the Clock master. The phasing of the slave is
accomplished with a resistor string tied to the PHSEL pin. More information is covered in the CLOCK
MASTER, PHSEL AND CLKIO CONFIGURATIONS section.
