2. Analog Devices: ADP2370 - 15V, 1.2A, high-efficiency, step-down converter.
3. Microchip: MCP16331 - 30V, 1A, high-efficiency, step-down regulator.
4. Infineon: IR3891 - 15V, 4A, highly integrated, step-down DC-DC converter.
These equivalents vary slightly in specifications, so compatibility should be verified for specific applications.
Features
Key features include a high-efficiency rating of up to 90% or more, achieved through its synchronous rectification architecture. It supports a load current of up to 4A, making it suitable for power-demanding applications. The TPS62136RGXR integrates a low RDSON MOSFET to minimize conduction losses, enhancing efficiency and thermal performance.
The converter supports Pulse Frequency Modulation (PFM) for light load efficiency and a power save mode to further reduce power consumption during low power conditions. It also features a soft-start function to prevent inrush current during startup, as well as protection features like overcurrent protection, over-temperature protection, and output discharge.
The device comes in a compact 16-pin VQFN package, making it suitable for space-constrained applications.
