AS8211HV

AS8211HV is a low-cost 150V high voltage DCDC BUCK chip

The AS8211HV is a high-performance, low-cost PWM controlled power switch suitable for off-line low-power step-down applications with simple peripheral circuits and fewer devices. At the same time, the built-in high voltage MOSFETs can improve the surge tolerance of the system. Different from the traditional PWM controller, the AS8211HV has no fixed clock drive MOSFETs, and the switching frequency of the system can be adjusted automatically with the change of load.

At the same time, the chip adopts multi-mode PWM control technology, which effectively simplifies the peripheral circuit design, improves the linear adjustment rate and load adjustment rate, and eliminates the audible noise in the system work. In addition, the peak current detection threshold inside the chip can be automatically adjusted according to the actual load condition, which can effectively reduce the standby power consumption under no-load condition.
