The ET8131 is a high-performance synchronous Buck DC-DC converter that delivers up to 3A of output current. It accepts a wide input voltage from 4.5V to 17V and provides an adjustable output from 0.76V to 7V. With a fixed 580kHz switching frequency, it offers an excellent balance between efficiency and external component size. Housed in a compact SOT-23-6 package, the ET8131 is ideal for space-constrained applications requiring higher load currents.
- 3A Output Capability: Supports higher current loads compared to standard 2A converters, expanding application possibilities.
- High Efficiency: Synchronous design minimizes power dissipation, improving thermal performance in compact designs.
- Stable Operation: Fixed 580kHz frequency provides predictable EMI and consistent performance across load conditions.
- Small Footprint: SOT-23-6 package enables dense PCB layouts for portable and embedded systems.
High-Performance Portable Devices
For devices requiring higher current, the ET8131 delivers up to 3A from a 5V or 12V input. This makes it suitable for powering application processors, FPGAs, and high-power wireless modules in portable equipment.
Point-of-Load (POL) Regulation
In multi-rail systems, the ET8131 can efficiently step down a 12V bus to a lower voltage for local loads. Its 580kHz frequency allows for a compact POL design with minimal external components.
Gaming and Computing Peripherals
Power hungry peripherals like gaming consoles, external GPUs, and high-speed SSDs benefit from the ET8131's 3A capability and high efficiency, reducing thermal stress in enclosed spaces.
Smart Home Hubs
Smart home devices with multiple radios and sensors require stable power. The ET8131 provides a clean, efficient supply from a 12V adapter, ensuring reliable operation of Zigbee, Wi-Fi, and Thread modules.
Test and Measurement Equipment
In bench instruments, the ET8131 offers precise voltage regulation for analog and digital circuits. The low output ripple at 580kHz helps maintain signal integrity in sensitive measurements.
