ZHCSKY4B November 2018 – December 2020 TPS55288
PRODUCTION DATA
In light load condition, the TPS55288 can work in PFM or forced PWM mode to meet different application requirements. The 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.
