DESCRIPTION

HM9221 is a high-efficiency, high-current fixed-frequency PWM current Type DC-DC boost chip. The built-in power MOS tube of HM9221 provides a maximum input current of 6A, Meet the needs of large current loads. The external soft start pin of HM9221, The soft start time of the chip can be easily adjusted to reduce the system startup time The impact current of the time. External compensation pins can optimize the loop of the chip In response, reduce the output ripple of the chip when the load fluctuates. HM9221 complete open circuit protection function, short circuit protection function, protection The chip will not be damaged under abnormal conditions, which improves the reliability of the system. HM9221 provides ESOP8 package with enhanced heat dissipation
