Switched-mode power supply |
摘要 |
A switched-mode power supply (SMPS) uses an equivalent inductor of bonding wire(s) and lead frame(s) to replace a traditional external inductor. A current-controlled pulse width modulation (PWM) modulator and a current-controlled pulse frequency modulation (PFM) modulator are optionally employed for high frequency switching, so as to mate a low inductance value of the bonding wire(s) and lead frame(s) and achieve reduced cost, low power consumption and low complexity.
