ZHCSMV3A December 2020 – December 2021 TPS552882-Q1
PRODUCTION DATA
In light load condition, the TPS552882-Q1 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.
