General Description
The RT7296F 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
RT7296F provides power good pin to be an output
voltage ready indicator. A cycle-by-cycle current limit
function provides protection against shorted output.
The RT7296F provides complete protection functions
such as input undervoltage lockout, output
undervoltage protection, overcurrent protection, and
thermal shutdown. The PWM frequency is adjustable
by the EN/SYNC pin. The RT7296F is available in the
TSOT-23-8 (FC) package.
The recommended junction temperature range is
−40C to 125C and ambient temperature range is
−40C to 85C.
