The PLE series of metal power inductors made by TDK are high-efficiency, ultra-compact components with low-leakage magnetic flux that are effective when operating with small batteries installed in wearable devices. By using TDK-developed structural designs and newly developed materials as well as thin-film processes, rated current of 500 mA with high impedance of 2,2 μH is achieved in a component with a size of 1,0 x 0,6 x 0,7 mm.
Wearable devices powered by small batteries require low power consumption, so pulse frequency modulation (PFM) is used as the power supply drive method. PFM has the advantage of lower power consumption due to lower DC bias current compared to pulse width modulation (PWM), but has higher AC bias current. Therefore, the ACR (AC resistance) characteristic becomes important, and by using high-Q, low-ACR inductors it is possible to achieve high power supply efficiency.
