Cxsu6302 cxsu6303 series products are a high efficiency low ripple high frequency PFM boost DC-DC converter Only four products are needed

Cxsu6302 cxsu6303 series products are a high efficiency, low ripple, high frequency PFM boost DC-DC converter. Only four products are needed
Peripheral components can transform and boost the low input battery voltage to the required working voltage, which is very suitable for portable 1-4 ordinary electricity
Pool applications. The circuit adopts a high-performance, low-power reference circuit structure, and introduces correction technology in the production to ensure the output power
High output accuracy and low temperature drift. The output voltage accuracy is better than ?2.5%, and the highest efficiency is 89%. There are four jtqx2303 series products in total
Package forms: SOT23, SOT23-5, sot89-3 and TO-92. Among them, the SOT23-5 package is equipped with an en enabling terminal to control the converter
When the en enable end input is at low power level, the chip is in the off power saving state and the power consumption is minimized.

Cxsu6302 cxsu6303 series products are a high efficiency low ripple high frequency PFM boost DC-DC converter Only four products are needed
