    产 品 说 明
The RT8075 is a high efficiency Pulse-Width-Modulated
(PWM) dual step-down DC/DC converter. Capable of
delivering up to 1A output current over a wide input voltage
range from 2.5V to 5.5V, the RT8075 is ideally suited for
portable electronic devices that are powered from 1-cell
Li-ion battery or from other power sources such as cellular
phones, PDAs, PC WLAN card and hand-held devices.
Three operating modes are available including : PWM
mode, Low Dropout Mode and shut-down mode. The
Internal synchronous rectifier with low RDS(ON) dramatically
reduces conduction loss at PWM mode. No external
Schottky diode is required in practical application. The
RT8075 enters Low Dropout mode when normal PWM
cannot provide regulated output voltage by continuously
turning on the upper P-MOSFET. The RT8075 enters shutdown
mode and consumes less than 0.1μA when the EN
pin is pulled low.
The switching ripple is easily smoothed-out by small
package filtering elements due to the fixed operating
frequency of 1.25MHz. The RT8075 is available in the
WDFN-10L 3x3 package.
