产品名称:85KHz, 2A PWM Buck DC/DC Converter 85KHz, 2A PWM降压DC/DC转换器

产品型号:AX3007A

产品描述:

The AX3007A series are monolithic IC designed for a step-down DC/DC

converter, and own the ability of driving a 2A load without additional transistor. It

saves board space. The external shutdown function can be controlled by logic level

and then come into standby mode. The internal compensation 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 switching frequency will

be reduced.

The AX3007A series operates at a switching frequency of 85KHz thus allow

smaller sized filter components than what would be needed with lower frequency

switching regulators. The output version included fixed 3.3V, 5V, 12V, and an

adjustable type. The chips are available in standard SOP8, SOP8-EP and TO252-5L

packages.
