Richtek RT7299B | Demoboard EVB_RT7299BHGQW-00

Description

The RT7299BHGQW is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to8A output current from a 4.5V to 18V input supply. The RT7299BHGQW current-mode architecture with externalcompensation allows 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 surgeduring startup. Fault condition protections include output under-voltage protection, output over-voltage protection,and over-temperature protection. The low current shutdown mode provides output disconnection, enabling easypower management in battery-powered systems.
