LP6225

LP6225 is an asynchronous boost chip controlled by peak current mode, with a fixed switching frequency of 900Khz.The compensation network is integrated internally and no external components are needed to compensate. The integrated soft start circuit can effectively control the inrush current during startup and prevent the battery or external power supply voltage from being pulled down. In addition, with the Output voltage can be programmed through external resistors to respond to different power supply system requirements.LP6225 can automatically enter PFM mode under light load to improving the conversion efficiency. With the load current increasing, the chip enters PWM mode, in which the frequency band of output ripple is relatively fixed and the conversion efficiency will behighly. The LP6225 integrates under-voltage, overcurrent, over-temperature and other protection functions.The LP6225 provides the smaller SOT23-6 package.
