Description
The MP1492 is a fully integrated, high–efficiency 2A synchronous rectified step-down converter. The MP1492 operates at high efficiency over a wide output current load range. Adaptive Constant-On-Time (COT) controlmode provides fast transient response, eases loop stabilization, and operates with a low-cost electrolytic capacitor.
The MP1492 requires a minimum number of readily available standard external components and is available in an 8-pin SOIC ROHS compliant package.
Features
- Wide 4.2V to 16V Operating Input Range
- 2A Output Current
- Adaptive COT for Fast TransientResponse
- Low RDS (ON) Internal Power MOSFETs
- Proprietary Switching Loss Reduction Technique
- Programmable Switching Frequency
- OCP, SCP, OVP, UVP Protection and Thermal Shutdown
- Output Adjustable from 0.805V to 13V
Typical applications
- Flat Panel Television and Monitors
- Digital Set Top Boxes
- Distributed Power Systems
