OptiMOS™ 5: When to use TOLT devices over traditional TOLL devices? (KA-03296)
Traditional TOLL packages are rated up to 300 A, equivalent to TOLT. However TOLL devices dissipate heat through the PCB, which has the heatsink mounted underneath. This limits the thermal performance and power handling ability of the system. TOLT devices overcome this limitation with top-side cooling, thereby allowing the customer to achieve higher power capability.
