R E F E R E N C E D E S I G N IRDCiP2021C-1
International Rectifier ? 233 Kansas Street, El Segundo, CA 90245 USA
IRDCiP2021C-1: 500kHz, 40A, Single Output,
Dual Phase Synchronous Buck Converter
Featuring iP2021C and IR3623M
Overview
This reference design is capable of delivering a continuous current of 40A,
single output without heatsink at an ambient temperature of 45oC and airflow of
200LFM. Fig. 4 – Fig. 16 provide performance graphs, thermal images, and
waveforms. Fig. 1 – Fig. 3 are provided to engineers as design references for
implementing an IR3623+iP2021C solution.
The components installed on this demoboard were selected based on operation
at an input voltage of 12V (+/-10%), a switching frequency of 500kHz (+/-
15%), and an output voltage of 1.2V. Major 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 iP2021C and IR3623 datasheets for more
information.
IRDCiP2021C-1 Recommended Operating Conditions
(refer to the iP2021C datasheet for maximum operating conditions)
Input voltage: 8.5V – 14.5V
Output voltage: 0.8 – 5V
Switching Freq: 500kHz
Output current: This reference design is capable of delivering a continuous current of 40A without heatsink at an
ambient temperature of 45oC and airflow of 200LFM.
Demoboard Quick Start Guide
Initial Settings:
VOUT is set to 1.2V, but can be adjusted from 0.8V to 5V by changing the values of R11 and R15 according to the following
formula:
R11 = R15 = (10k * 0.8) / (VOUT - 0.8)
The switching frequency is set to 500kHz, but can be adjusted by changing the value of R26. See Fig. 4 for the relationship
between R26 and the switching frequency.
