ZHCSSS8 august 2023 TPS552872
PRODUCTION DATA
In light load condition, the TPS552872 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.
