Apparatus Without Intermediate Ac Conversion TRIZ Cases
- Dual Output Charge Pump Sharing Flying Capacitance
A charge pump circuit shares a single flying capacitance between boost and buck stages to generate 2xVin and Vin/2 outputs.
- Voltage Generating Circuit With NTC Thermistor for Display Reliability
An NTC thermistor in the second charge pumping part lowers resistance as temperature rises, reducing power consumption and preventing initial driving defects.
- Multi-mode Charge Pump with Shared Flyback Capacitor
Dynamic turn-on resistance control stabilizes output voltages across varying load currents in mobile devices.
- Charge Pump Switchable Impedance Startup Ripple Control
A charge pump employs a switchable impedance to lower startup delay while reducing output voltage ripple during steady-state operation.
- Adapter Component for Dynamic AC DC Power Mode Selection
An adapter component with dual driving units selectively outputs AC or DC power based on detected device parameters.
- Voltage Booster Circuit Segmentation for Ripple Reduction
Segmenting charge pumps into dedicated voltage and current paths eliminates load interference to stabilize output voltage.
- Transformerless Switched Converter for Power Domain Isolation
A transformerless switched converter system uses bidirectional current blocking circuitry to isolate power domains.
- Capacitive Coupled Input Transfer Gates for Precision Amplifiers
Capacitor-based shift circuits adjust clock voltage levels to match common mode inputs without altering frequency or edge characteristics.
