AX3021 Datasheet | AXElite

200KHz, 1.5A PWM Buck DC/DC Converter  GENERAL DESCRIPTION The AX3021 series are monolithic IC designed for a step-down DC/DC converter, and own the ability of driving a 1.5A load without additional transistor. It saves board space. The external shutdown function can be controlled by logic level and then e into standby mode. The internal pensation makes feedback control having good line and load regulation without external design. Regarding protected function, thermal shutdown is to prevent over temperature operating from damage, and current limit is against over current operating of the output switch. If current limit function occurs and VFB is down below 0.5V, the...
