概要 |
This study introduces the design of a Discontinuous Conduction Mode (DCM) Single-Input Dual-Output DCDC Pulse Frequency Modulation (PFM) Boost Converter with Zero Current Detection (ZCD) aimed at addr...essing the diverse power supply needs of modern electronics. The converter, a synchronous boost type, efficiently produces two distinct output voltages (3.3 V and 5 V) from a single 1.8 V input, simplifying the control system requirements. Utilizing a 180 nm CMOS process for the control circuits, the design ensures seamless integration and efficient performance. Simulation results confirm the successful voltage amplification, achieving the target outputs of 3.3 V and 5 V. Additionally, the converter attains a peak efficiency of 82.93% across a load current range of 100μA to 1mA, making it ideal for a wide range of electronic applications. Key benefits of this design include its dual-output functionality, high efficiency, and compact integration, which collectively enhance the versatility and energy efficiency of power management solutions.続きを見る
