非隔離高壓Buck-CN2201P

The CN2201P is a current mode monolithic buck switching regulator.Operating with an input range of 4.7-40V,the CN2201P delivers 1A of continuous output current with two integrated N-Channel MOSFETS. The internal synchronous power switches provide high efficiency without the use of an external Schottky diode. CN2201P also employs a proprietary control scheme that switches the device into a power save mode during light load, thereby extending the range of high efficiency operation. An OVP function protects the IC itself and Thermal shutdown provides reliable,fault-tolerant operation. With this OVP function, the IC can stand off input voltage as 42V, making it an ideal solution for industrial applications such as smart meters as well as automotive applications.A 3uA shutdown mode quiescent current allows use in a battery-powered applications.
