Key Features

The LTC3850EGN#TRPBF is a high-efficiency, dual-phase synchronous step-down switching controller from Linear Technology. It drives all N-channel power MOSFET stages and operates with a constant-frequency current mode control architecture. The two output stages function out of phase, reducing input ripple and power supply noise. Its wide input voltage range of 4V to 24V (30V for the LTC3850I) supports various battery and bus voltage systems.

This controller features OPTI-LOOP® compensation, allowing for optimized transient response across different output capacitances and ESR values. The precision 0.8V reference ensures ±1% output accuracy, while the integrated power good output indicator provides system monitoring. Additionally, the switching frequency can be locked to an external clock up to 780kHz, giving designers flexibility in power system optimization.

Applications

Notebook and palmtop computers
Portable instruments
Battery-operated digital devices
DC power distribution systems
