User's Guide SNVU570A – December 2017 – Revised June 2018 TPSM846C24 70-A Parallel Operation Evaluation Module This user’s guide contains information for the TPSM846C24DEVM-007 evaluation module (BSR007). Also included are the performance specifications, schematic, bill of materials (BOM), and layout of the EVM. -
Page 2: Description
The TPSM846C24 device is a synchronous buck power module designed to provide up to 35-A of output current. The TPSM846C24 can be paralled with two devices to achieve output current up to 70 A. The TPSM846C24 is a highly integrated, DC-DC power module that combines a 35-A DC/DC converter with power MOSFETs, a shielded inductor, some input and output capacitors, and passives into a low profile package. -
Page 3: Test Point Descriptions
(C28–C31). The default jumper load is the 2000 µF position. When two TPSM846C24 devices are paralleled, the SYNC pins of the Master and the Slave must be supplied with a 50% duty cycle external clock signal at the desired switching frequency. A 500-kHz clock is present on the EVM which supplies the required 50% duty cycle signal. -
Page 4: Operation Notes
CLK test point must be 2 × the required frequency. The device can be synchronized to an external clock over the frequency range of 300 kHz to 1 MHz. Refer to TPSM846C24 4.5-V to 15-V Input, 0.5-V to 2.0-V Output, 35-A Power Module for further information on synchronization. -
