CXSU 63297 is a simple and easy-to-use PFM mode boost DC-DC conversion control integrated circuit, particularly suitable for low-cost, miniaturized applications. The input voltage range is 2.7V to 6.5V, and the output voltage is fixed at 9V with an accuracy of ± 1%. CXSU63297 operates with a current of only 32 microamperes at 5V input voltage, making it very suitable for battery powered applications. The CXSU 63297M operating mode can achieve good conversion efficiency over a wide range of input voltage and output current. The conduction time and turn off time of off chip N-channel MOSFETs have also been fully optimized, making them very suitable for miniaturization of inductors and filtering capacitors. The chip enables the input terminal to put CXSU 63297 into an extremely low-power shutdown mode. CXSU63297 adopts the SOT-23 package with 6 pins.
