Optimized Design of a DCM Single-Input Dual-Output DC-DC PFM Boost Converter Featuring Zero Current Detection

This study introduces the design of a Discontinuous Conduction Mode (DCM) Single-Input Dual-Output DC-DC Pulse Frequency Modulation (PFM) Boost Converter with Zero Current Detection (ZCD) aimed at addressing 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 100A 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.
