EVB_RT7294CGJ6F: 1.2V @ 2.5A, 4.3 ~ 18Vin

Summary

The EVB_RT7294CGJ6F is a synchronous step-down converter with Advanced Constant On-Time (ACOT) mode control. The ACOT provides a very fast transient response with few external components. The low impedance internal MOSFET supports high efficiency operation with wide input voltage range from 4.3V to 18V. The proprietary circuit of the RT7294C enables to support all ceramic capacitors. The output voltage can be adjusted between 0.6V and 8V.

The RT7294C also provides output under voltage protection and thermal shutdown protection. The low current (<4µA) shutdown mode provides output disconnection, enabling easy power management in battery-powered systems. The RT7294C is available in TSOT-23-6 FCOL (Flip-Chip-On-Lead) package.
