Beschreibung
- Typical Application Circuit for LTC3890EUH High Efficiency Dual 8.5V/3.3V Output Step-Down Converter. The LTC3890 is a high performance dual step-down switching regulator DC/DC controller that drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows a phase lockable frequency of up to 850kHz. Power loss and noise due to the ESR of the input capacitor are minimized by operating the two controller output stages out-of-phase
