Inductorless SRs, also called “charge pump converters” (figure 2), have been known to be less efficient than their inductor-based counterparts when used with a variable input voltage. However, this is ...

STAR4003 is designed in a TSMC 40nm process with 3.3V tolerant devices. It outputs an open loop doubled voltage from the input supply. The IP integrates two NMOS power switches and two PMOS power ...
