International Rectifier ? 233 Kansas Street, El Segundo, CA 90245 USA
IRDCiP1206-B: 300 kHz, Dual Output, Synchronous
Buck Converter using iP1206
Overview
This reference design is capable of delivering a continuous current of 30A; (i.e.
15A max. per output channel) at an ambient temperature of 45oC and with
200LFM of airflow. Figures 1–24 provide performance graphs, thermal images,
and waveforms. Figures 25–35, and Table 1 are provided to engineers as
design references for implementing an iP1206 solution. The components
installed on this demoboard were selected based on operation at an input
voltage of 12V and at a switching frequency of 300 kHz. Changes from these
set points may require optimizing the control loop and/or adjusting the values of
input/output filters in order to meet the user’s specific application requirements.
Refer to the iP1206 datasheet User Design Guidelines section for more
information.
Note: The 16-pin connector (CON1) is used only for production test purposes
and should not be used for evaluation of this demoboard.
Demoboard Quick Start Guide
Initial Settings:
VOUT 1 is set to 2.5V, but can be adjusted from 0.8V to 5.5V by changing the values of R5 and R6 according to the following
formula:
R5 = R6 = (10.0k * 0.8) / (VOUT - 0.8)
VOUT 2 is set to 1.5V, but can be adjusted from 0.8V to 5.5V by changing the values of R5 and R6 according to the following
formula:
R15 = R16 = (10.0k * 0.8) / (VOUT - 0.8)
The switching frequency is set to 300 kHz, but can be adjusted by changing the value of R T . The graph in Figure 26 shows the
relationship between R T and the switching frequency.
Power Up Procedure:
1. Apply input voltage across VIN and PGND.
2. Apply load across VOUT 1 pads and PGND pads and across VOUT 2 pads and PGND pads
3. Adjust load to desired level. See recommendations below.
Simultaneous and Ratiometric Startup and Shutdown:
Refer to the iP1206PbF datasheet for instructions on using the IRDCiP1206-B board outputs in either ratiometric or simultaneous
operation mode.
