Application Information (continued)
If the controller has free running operation (in clock master mode) before receiving the external clock, the
switching frequency is set by connecting a resistor from the RT pin to GND. In order to receive the external
clock, the PHSEL pin should be connected to GND to disable the output of CLKIO pin. A 500-
Ω resistor is
recommended to be placed between the external clock and the CLKIO pin. When dynamically shorting the RT
pin to BP5 through a switch, the controller switches to clock slave mode and starts to synchronize to the external
clock.
9.1.2 Split Input Voltage Operation
It may be advantageous to operate a master controller’s power stages from VIN 1, different from the slave
controller(s) power stages, VIN 2 where VIN1 > VIN 2. This enables the system designer to optimize the current
taken from the system input voltages. In order to balance the output currents, a programmed offset is applied to
ILIM2 of the slave controller(s). The voltage on this pin sets the offset current for channel 2.
The ramp offset is determined by a resistor, RSET, connected to the ILIM2 pin of the slave, and is given by:

9.1.3 Configuring Single and Multiple ICs
The controller may be configured for a single output, 2-phase mode or a dual output voltage mode. In the dual
output mode the input voltages and the output voltages are independent of each other. In 2-phase mode the
input voltages and output voltages are tied together, respectively and certain other pins must be configured. The
two phases of a single controller are always 180° out-of-phase. The entry in Table 3 that refer to "TO
NETWORK" means the normal resistor-capacitor network used for control loop compensation. The other entries
refer to components that are typically connected to the device pin.

9.1.3.1 Single Device Operation
A single controller may be configured as a 2-phase or dual output. A summary of the modes and device pin
connections for a single controller is given in Table 3. The basic schematic of a single controller operating in a 2-
phase mode is shown in Figure 17. The dual output schematic is shown in Figure 18.
