Description
The LTC®1649CS is a DC DC switching controller that is used to regulate very low voltage supply for high efficiency and high power applications. It has an input voltage range of 2.7V-5V and provides a regulated output voltage range of 1.26V-2.5V with a load current of up to 20A. It uses a pair of standard 5V logic-level N-channel external MOSFETs, which eliminates the need for expensive P-channel or super-low-threshold devices. It has a typical efficiency above 90% from 1A to 10A load, making it ideal for low voltage microprocessors and logic and high power, low voltage regulators.
Specifications and features
Features:
- High power 3.3V to 1.xV-2.xV switching regulator controller: Up to 20A output
- All N-channel external MOSFETs
- Provides 5V MOSFET gate drive with 3.3V input
- Excellent output regulation: ±1% over line, load and temperature variations
- Constant frequency operation minimizes inductor size
- High efficiency: Over 90% possible
- No low-value sense resistor needed
- Available in 16-lead SO package
Application Scenarios
The LTC1649CS is ideal for the following applications:
- low voltage microprocessors and logic
- low input voltage power supplies
- high power, low voltage regulators
- local regulation for multiple voltage distributed power systems
Comparison
