Conv DC-DC 1.5V to 18V Synchronous Step Down Quad-Out 0.5V to 16.2V 5A/5A/5A/5A 48-Pin LQFN EP Tray
Analog DevicesLT7200S: Quad 18V, ±5A Synchronous Monolithic Step-Down Regulator
The LT7200S is a quad-channel, high-efficiency monolithic synchronous buck regulator, capable of sinking/sourcing 5A to the load per channel. Its multichannel flexibility is ideal for powering complex systems with a compact layout. The operating supply voltage range is from 2.9V to 18V, making it suitable for various supply applications from a 3.3V, 5V to 12V supply.
Key Features and Benefits
- High efficiency at high switching frequencies across entire load
- Accurate and highly configurable with multichannel sequencing, tracking, and output paralleling
- Wide output voltage range for greater flexibility
Applications
- Data Center: Distributed power systems, server power applications
- Communications: FGPA point of load
- Industrial Automation: Point of load power supplies, high accuracy power supply for FPGA, power supply with sequencing
- Instrumentation and Measurement: Small form factor power supply
Evaluation Board
The LT7200S can be evaluated with the DC2851A.
