Cxsu6300 is a high efficiency, high frequency and low noise Synchronous Buck DC / DC voltage regulator, which is suitable for the application of single lithium battery power supply. The input voltage range

Cxsu6300 is a high efficiency, high frequency and low noise Synchronous Buck DC / DC voltage regulator, which is suitable for the application of single lithium battery power supply. The input voltage range of 2.5V to 5.5V enables the cxsu6300 to be truly suitable for the application of a single lithium battery power supply, and the output voltage can be adjusted in the range of 5.5V to 0.6V. The working current is only 20 μ a, which is as low as 1 μ a when it is turned off. 100% duty cycle provides LDO operation, which can extend the life of lithium battery in portable system. Because the internal switch frequency is 1.4mhz, the external inductance and capacitance can use very small chip inductance and capacitance. Synchronous switch is used in the interior to improve the frequency without additional Schottky diode
