iP1001
iP1001 Reference Design
The schematics in Fig.10a & 10b and complete Bill
of Materials in Table 4 are provided as a reference
design to enable a preliminary evaluation of iP1001.
They represent a simple method of applying the
iP1001 solution in a synchronous buck topology.
Fig. 10a shows the implementation for <5V IN
nominal applications, and Fig. 10b shows the
implementation for 5V IN - 12V IN nominal
applications.
The connection pins are provided through the solder
balls on the bottom layer of the package. A total
power supply solution is presented with the addition
of inductor L1 and the output capacitors C11-C14.
Input capacitors C1-C10 are for bypassing in the
5V IN - 12V IN application, but only C1-C3 are required
for <5V IN applications (refer to the BOM for values).
Switches 1-5 of SW1 are used to program the output
voltage. Refer to the VID table provided in this
datasheet for the code that corresponds to the
desired output voltage. Resistors R2 & R4 need to
be removed for operation at standard VID levels
(0.925V - 2.0V, leave R3 = 0 ? ). Switch 8 of SW1
enables the output when floating (internally pulled
high). The 5V V DD power terminal and input power
terminals are provided as separate inputs. They
can be connected together if the application
requires only 5V nominal input voltage.
The reference design also offers a higher output
voltage option for greater than 2.0V, up to 3.3V. For
output voltages above 2V, the DAC setting must be
set to 2V, and then select resistors R3 & R4 per
Equation 1 on page 10 for the desired output volt-
age. Remove R5 and connect V F to V FS through R2,
where R2= 0 ?. In this case, GNDS should be refer-
enced to PGND. Tighter regulation can be achieved
by using resistors with less than 1% tolerance. For
Vin < 5V and Vout > 2V, the frequency select pin
(FREQ) must be set to 200kHz (connected to V DD ).
For applications with V IN < 5V and where there is no
auxiliary 5V available, connections JP2 and JP3
must be provided in order to enable the boost cir-
cuit. This will provide 5V V DD necessary for the
iP1001 internal logic to function. The boost circuit
will convert 3.3V input voltage to 5V, to power the
V DD , and will provide enough power to supply the
internal logic for up to five iP1001 power blocks.
