SLVSFQ7A December 2020 – December 2021 TPS55288-Q1
PRODUCTION DATA
In light load condition, the TPS55288-Q1 can work in PFM or forced PWM mode to meet different application requirements. PFM mode decreases switching frequency to reduce the switching loss thus it gets high efficiency at light load condition. The FPWM mode keeps the switching frequency unchanged to avoid undesired low switching frequency but the efficiency becomes lower than that of PFM mode.
