RT6296E
2A, 17V Current Mode Synchronous Step-Down Converter
General Description
The RT6296E is a high-efficiency, 2A current mode
synchronous step-down DC/DC converter with a wide input
voltage range from 6V to 17V. The device integrates 100mΩ
high-side and 40mΩ 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 RT6296E
provides complete protection functions such as input under-
voltage lockout, output under-voltage protection, over-
current protection, and thermal shutdown. The RT6296E
is available in the TSOT-23-8 (FC) package.
