Overview
RT7296B 3A, 17V Current Mode Synchronous Step-Down Converter General Description The RT7296B is a high-efficiency, 3A current mode synchronous step-down DC-DC converter with a wide input voltage range from 4.
5V to 17V.
The device integrates 80m high-side and 30m low-side MOSFETs to achieve high efficiency conversion.
The current mode control architecture supports fast transient response and internal compensation.
A cycle-by-cycle current limit function provides protection against shorted output.
The RT7296B provides complete protection functions such as input under-voltage lockout, output under-voltage protection, over-current protection, and thermal shutdown.
The PWM frequency is adjustable by the EN/SYNC pin.
The RT7296B is available in the TSOT-23-8 (FC) package.
