ET8134M

Overview

The ET8134M is a synchronous buck switching regulator IC from ETEK Microelectronics. It integrates high-side and low-side power FETs with on-resistances of 130mΩ and 100mΩ, respectively. The device operates within an input voltage range of 4.5V to 38V and delivers up to 3A of output current. It features an adjustable output voltage range from 0.923V to 7.0V. The regulator utilizes ACOT mode control architecture to ensure fast transient response. Typical efficiency exceeds 93%, with a quiescent current of 300µA.

Feature Summary

Integrates high-side and low-side power FETs for compact design
Utilizes ACOT mode control for rapid transient response
Supports wide input voltage range up to 38V

Applications

Industrial equipment power supplies
Consumer electronics systems
General-purpose DC-DC conversion

Procurement Notes

Verify the specific suffix 'M' against the manufacturer's official documentation to confirm pinout compatibility and package type (ESOP8). Ensure the selected variant matches the required thermal performance and electrical specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when a wide input voltage range up to 38V is required alongside high current capability. The integrated FETs and ACOT control make it suitable for applications demanding fast transient response without external compensation components. Verify that the output voltage setting falls within the 0.923V to 7.0V adjustable range.

Part Context

The ET8134M belongs to ETEK Microelectronics' line of synchronous buck regulators designed for power management in analog and digital circuits. It is part of a family offering various current ratings and input voltage ranges, targeting mobile, industrial, and consumer markets with high integration and efficiency.

Replacement Considerations

Consult official substitution lists for compatible parts such as the ET8134 or other ET81xx series variants. Verify pin-to-pin compatibility and electrical parameter alignment before replacing.
