EVB_RT8008GB

The EVB_RT8008GB is an evaluation board for RT8008GB device. The RT8008GB is a high efficiency pulse width modulated (PWM) step down DC to DC converter. Capable of delivering 600mA output current over an input voltage range of 2.5V to 5.5V, the RT8008GB is ideally suited for portable electronic devices that are powered from one cell Li ion battery (or from other power sources within that range). An internal synchronous rectifier with low RDS(ON) dramatically reduces conduction losses in PWM mode. No external schottky diode is required in practical applications. The RT8008GB automatically turns off the synchronous rectifier when the inductor current is low entering discontinuous PFM mode to increase efficiency at light loads. The RT8008GB enters low dropout mode when normal PWM operation cannot regulate the output voltage, turning on the upper P MOSFET continuously. The RT8008GB enters shutdown mode and consumes less than 0.1µA when EN pin is pulled low.
