A 91.6% Peak Efficiency Time-Domain-Controlled Single-Inductor Triple-Output Step-Up Converter with ±7.5 to ±12V Bipolar Output Voltages
This paper presents a time-domain-controlled (TDC) single-inductor triple-output (SITO) step-up converter with enhanced load transient response. The proposed converter can convert 2.7 to 5V input voltage into a pair of bipolar high output voltages ranging from ±7.5 to ±12V and a 5V positive output voltage with a maximum output power of 9.6W. By using the time-domain controller and an ADC-assisted fast settling loop, the converter exhibits a fast transient response with low undershoot/overshoot voltages. The proposed converter was fabricated in a 180nm BCD process. With a 2MHz switching frequency, the converter achieves a peak conversion efficiency of 91.6% at an output power of 2.25W.
