- Hysteretic regulators provide high performance at low costHysteretic voltage regulators offer the potential advantages of simplicity, fast response, 100%-duty-cycle operation, high efficiency at light loading, and low cost. They need no loop-compensation components to add...08-02-2023
- Wide-range regulator delivers 12V, 3A output from 16 to 100V sourceSynchronous buck regulators offer high efficiency and are popular in applications in which available input voltages are 12 V or less. However, as input voltage approaches 100 V, wide-range-regulator design...12-07-2022
- Bipolar transistor boosts switcher's current by 12 timesThe circuit in Figure 1 uses a minimal number of external parts to raise the maximum output current of a 0.5 A buck switching-regulator IC to more than 6 A. The circuit accommodates input voltages...03-07-2022
- Boost 3.3V to 5V with Tiny Audio AmplifierThis charge-pump circuit quietly converts a 3.3 V source to 5 V at 500 mA (Figure 1 and Figure 2). LM4871LD power amplifier makes this design idea both possible and practical, thanks to its low output resistance, low...10-12-2018
