Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
General Description
The RT8290 is a high efficiency synchronous step-down DC/DC converter that can
deliver up to 3A output current from 4.5V to 23V input supply. The RT8290's
current mode architecture and external compensation allow the transient
response to be optimized over a wide range of loads and output capacitors.
Cycle-by-cycle current limit provides protection against shorted outputs and
soft-start eliminates input current surge during start-up. The RT8290 also
provides output under voltage protection and thermal shutdown protection. The
low current (<3μA) shutdown
mode provides output disconnection, enabling easy power management in battery-
powered systems. The RT8290 is awailable in an SOP-8 (Exposed Pad) package.
