EVB_RT8296AHZSP: 3.3V @ 3A, 4.5 ~ 23Vin

Summary

The RT8296A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.5V to 23V input supply. The RT8296A'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 RT8296A 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 RT8296A is available in an SOP-8 (Exposed Pad) package.

Features:

±1.5% High Accuracy Feedback Voltage
Integrated N-MOSFET Switches
Current Mode Control
Up to 95% Efficiency
Stable with Low-ESR Ceramic Output Capacitors
