With an input operating voltage range from 3 V to 36 V and rated output current from 6 A to 8 A, the TPSM63608 and TPSM63610 family of synchronous buck power modules provides flexibility, scalability, and optimized solution size for a wide range of applications. With integrated power MOSFETs, buck inductor and PWM controller, these modules enable DC/DC solutions with high density, low EMI, and increased flexibility. Available EMI mitigation features include dual random spread spectrum (DRSS), RBOOT-configured switch-node slew rate control, and integrated input bypass capacitors.

TPSM636108 A

The TPSM63610EVM uses the TPSM63610 easy-to-use synchronous buck module IC with a wide output voltage range of 1 V to 20 V and an output current up to 8 A. The default output voltage of the EVM is set to 5 V can be adjusted to 3.3 V through a jumper setting.

The solution supports adjustable input voltage UVLO for application-specific power-up and power-down requirements, external clock synchronization to mitigate beat frequencies in noise-sensitive applications, PGOOD indicator for sequencing and output voltage monitoring, pin-selectable spread spectrum control for EMI mitigation, and pin selectable MODE control for light-load performance with AUTO mode or fixed switching frequency with FPWM mode.
