Overview
RT7296A 3A, 17V Current Mode Synchronous Step-Down Converter General Description The RT7296A 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.
The RT7296A provides TTH pin to adjust transition point from PSM to PWM in order to balance efficiency and output ripple.
A cycle-by-cycle current limit function provides protection against shorted output.
The RT7296A 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 RT7296A is available in the TSOT-23-8 (FC) package.
