Page 2: Description
The TPSM846C23 is a PMBus™ enabled, synchronous buck power module designed to provide up to 35 A of output current. The TPSM846C23 can be paralleled with two devices to achieve output current up to 70 A. The TPSM846C23 is a highly-integrated, PMBus-enabled 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 (C28–C31). The default jumper load is the 2000 µF position. When two TPSM846C23 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.

Output signal monitoring point for Bode plot analyzer. Switch node of the TPSM846C23 Master device (U1). Use an unshielded scope probe to monitor this point. Switch node of the TPSM846C23 Slave device (U2). Use an unshielded scope probe to monitor this point. -
Page 5: Operation Notes
This EVM is designed to be used with the USB-to-GPIO pod which enables communication over the PMBus. Jumper settings should not be changed while the module is powered. Permanent damage may occur.
