LTC3850EUF#PBF General Description
The LTC3850 is a high performance dual synchronous step-down switching regulator controller that drives all N-channel power MOSFET stages. A constant-frequency current mode architecture allows a phase-lockable frequency of up to 780kHz. Power loss and supply noise are minimized by operating the two controller output stages out of phase.
Features
- Dual, 180° Phased Controllers Reduce Required Input Capacitance and Power Supply Induced Noise
- High Efficiency: Up to 95%
- RSENSE or DCR Current Sensing
- ±1% 0.8V Output Voltage Accuracy
- Phase-Lockable Fixed Frequency 250kHz to 780kHz
- Supports Pre-Biased Output
Application
- Notebook and Palmtop Computers
- Portable Instruments
- Battery-Operated Digital Devices
- DC Power Distribution Systems
