 The CXSD62317 is a dual high-efficiency Pulse-Width-Modulated (PWM) step-down DC/DC 2TI嘉泰姆

converter. It is capable of delivering 1.5A output current over a wide input voltage range from 2TI嘉泰姆

2.3V to 6V, the CXSD62317 is ideally suited for portable electronic devices that are powered 2TI嘉泰姆

from 1-cell Li-ion battery or from other power sources within the range such as cellular phones,2TI嘉泰姆

PDAs and other handheld devices. Two operational modes are available. PWM/Low-Dropout 2TI嘉泰姆

auto-switch and shutdown modes. Internal synchronous rectifier with low RDS(ON) dramatically2TI嘉泰姆

 reduces conduction loss at PWM mode. No external Schottky diode is required in practical 2TI嘉泰姆

application. The CXSD62317 enters Low-Dropout mode when normal PWM cannot provide 2TI嘉泰姆

regulated output voltage by continuously turning on the upper PMOS. The CXSD62317 enter2TI嘉泰姆
