The TPSM843B22 evaluation module (EVM) is a synchronous buck power module designed to provide up to a 20 A output and is rated for 4 V to 18 V. The high-side and low-side MOSFETs are incorporated inside the TPSM843B22 package along with the gatedrive circuitry, inductor and basic passives. The low drain-to-source on-resistance of the MOSFET allows the TPSM843B22 to achieve high efficiencies and helps keep the junction temperature low at the rated output current. Fixed frequency advanced current mode control allows you to synchronize the module to an external clock source. An external divider allows for an adjustable output voltage. The TPSM843B22 FSEL and MSEL pins provide selectable switching frequency, soft-start time, current limit, and internal compensation.
